4 GENERAL 2 GENERAL 2.1 INTRODUCTION AND SCOPE This document is to assist those planning and/or undertaking the installation of IT network physical infrastructure at Lancaster University. This may be as part of a new building or refurbishment project, or smaller additions or changes to existing infrastructure, such as the installation of additional data lines. IT data network physical infrastructure here means Fibre-optic cables and their containment Structured copper cabling, i.e. CAT6 and CW1308, and its containment Communications ( Comms ) rooms including equipment racks, power, cooling, frames etc. This document is a specification and not a design, the design team(s) for the project must translate these specifications into a final design for written approval by ISS Network Contacts. This document does not specify the characteristics of active (powered) network equipment such as switches, routers, or Wi-Fi access points. It does specify passive infrastructure. This document does not specify network service characteristics, such as data network speeds, throughput capacities, Wi-Fi frequencies or signal strengths. 2.2 DOCUMENT LOCATION The most recent version of this document can always be found at DOCUMENT VERSION CONTROL Upon each revision of this document, it will be issued to the appropriate staff in the Professional Services division. It is the responsibility of each design team to ensure that they are using the most recent revision of the document. With respect to major building and refurbishment projects, if a new revision is released prior to tender stage, then it is expected that the design shall be modified to take account of the most recent specification. Any changes post-tender stage shall only be required following a change control request from ISS. 2.4 DECISION POINTS & EXCEPTIONS This document states the minimum requirements from ISS, all key design decision points must be discussed and accepted by ISS Network Contacts (see below). Where requirements within this document must be confirmed and agreed with ISS Network Contacts, these are marked with a symbol. However, if there is any lack of certainty regarding anything within 4

5 GENERAL this document, or relating to the network infrastructure installations in general, please contact one of the ISS Network Contacts. Should the Contractor identify any discrepancies between this specification and any design package, this shall immediately be drawn to the attention of ISS Network Contacts. For the purpose of any pricing, the Contractor shall allow for the most onerous services installation to meet the requirements. Any deviations of proposed design from the specifications in this document must be agreed in writing by ISS Network Contacts. 2.5 RECOMMENDED PRODUCT MODELS Where a recommended model is specified within the text of this document it is made either on the basis of a technical evaluation or procurement exercise. Any substitutions for the recommended models must be approved in writing by ISS Network Contacts. 2.6 ISS NETWORK CONTACTS Contact must be made with ISS early in the project planning process. ISS want to help all parties achieve successful, timely and high-quality project completion and will assist in any way possible. Where agreements and/or decisions need to be made with the ISS Network Contacts as specified within this document, this means initially the Site & Contractor Liaison staff as shown below, if unavailable the Escalation staff should be contacted Site & Contractor Liaison Paul Boyd Senior Network Specialist p.boyd@lancaster.ac.uk Richard du Feu Senior Network Specialist r.dufeu@lancaster.ac.uk Escalation Craig Macdonald Head of Networking c.macdonald@lancaster.ac.uk Mark Jameson Head of Technical Infrastructure m.jameson@lancaster.ac.uk 2.7 INSTALLATION STANDARDS All components must be installed, as a minimum, to the manufacturer s recommended standards. Where the ISS Specification(s) have a more stringent installation standard then they will take precedence over those of the manufacturer. 5

6 GENERAL 2.8 PERMIT TO WORK Lancaster University Facilities operates a Site Access Pass arrangement which must be completed prior to any works taking place on Campus, if the works are required to run within Plant Rooms, Service Risers or in close proximity to other services a Permit to Work is required. The only exception to this is in areas of campus temporarily under the control of external contractors during building works. In that case the appropriate valid permissions and permits to work must sought from the external building contractor in control of the area concerned and any induction they may deem necessary. Site Access & Permit to Works can be arranged by contacting the following: Site Access & Permit to Work Arrangements Simon Corless or Electrical Engineer s.corless@lancaster.ac.uk Andrew Newsham Electrical Maintenance Supervisor a.newsham@lancaster.ac.uk 2.9 CABLE TESTING AND ACCEPTANCE PROCEDURE In order for data cable installations to be accepted by ISS, three stages must be completed. See later sections for specific testing requirements. 1. On completion of installation, the contractor tests the data cable installations. 2. Contractor sends test results to ISS Network Contacts. 3. Witness testing of data lines by ISS Network Contacts. 6

7 3 COMMUNICATIONS (COMMS) ROOMS COMMUNICATIONS (COMMS) ROOMS 3.1 DEFINITION & USE Comms rooms are sometimes referred to as wiring closets or Premises Wire Distribution rooms. The specification below will clarify why we refer to rooms rather than closets. A comms room forms the termination point of structured copper cabling within a building, and may also contain fibre links to the main data centres on campus. The comms room must only be used for the housing of ISS Networking equipment used to support the delivery of network services to the building. For the avoidance of doubt this excludes anything not in the list below unless approved in writing from ISS Network Contacts; Data Cabinets CAT6 Cabling CAT6 Patch Panels Fibre Cabling Fibre Patch Panels UPS Data Switches CW1308 Cabling Voice Panels 3.2 PLANNING & DESIGN It is acknowledged that indicative sizes and locations of comms rooms are required in early-stage building design. However, the detailed requirements of comms rooms are generally finalised in later design stages, based on other information not available earlier (such as numbers of data lines). 3.3 LOCATION The comms room must be located so that the maximum electrical length of data lines emanating from it do not exceed 90.0 metres. It is strongly preferred that the number of comms rooms within a building is minimised. Where more than one comms room is required in a building, one room will be designated by ISS Network Contacts as the primary comms and the others as secondary. HALO fibre, which connects the building to the main campus datacentres, must be terminated in the primary comms room. All comms rooms within a building must be located so that they are accessed from a corridor or public space. It must not be necessary to access another space such as an office, meeting room or plant room in order to access the comms room, equally, access to other spaces must not be via the comms room. 3.4 SIZE The size of the comms room is a function of the number of lines that will be fed back to the room in the finished building. Each cabinet can house a maximum of 384 data lines. One additional cabinet footprint is required for future expansion. The cabinets in use are 800mm wide x 1000mm deep so by knowing the number of data lines to be installed, the minimum size of the comms room can be calculated. Example: 7

8 COMMUNICATIONS (COMMS) ROOMS 1000 datalines 384 = 2.6 = 3 cabinets required + 1 footprint 5250mm 1000mm 3000mm 1000mm Cabinet A Cabinet B Cabinet C 1000mm 1000mm The clearances in the drawing above must be clear space within the room; any protrusions into the room must be deducted from the available space. The door opening and delivery route to the room must be sized to allow the delivery of an 800 mm wide x 2.2 metre high cabinet. The loading of racks into the comms room should commence at the footprint furthest from the door opening. Cabinet A must be the left hand most cabinet when viewed from in front of the cabinet doors. 3.5 SECURITY The comms room must be fitted with a Grovsenor/Janus IDCe access control system (please refer to the ISS Access Control Specifications for full details). The IDCe must be located within the comms room. The comms room must be fitted with an Abloy EL560 lock mechanism configured to fail secure, no fire alarm interlink is required. A uniquely numbered lock barrel from the ISS Comms room suite must be fitted within the EL560 with internal thumb screw. Two keys must be supplied with each lock. There must be no vision panel fitted to the door. The room must be fitted with at least one heat/smoke detector connected to the main building fire alarm system. The door must only be labelled with room number and not specific function. 3.6 FINISHES Walls must be painted white or cream. Floors must be low dust, anti-static. Carpets will not be accepted. Where a raised floor is in use, prefinished vinyl tiles must be installed. 8

9 COMMUNICATIONS (COMMS) ROOMS 3.7 LIGHTING The room must be provided with high-temperature fluorescent or LED strip lighting to provide 500lux at floor level. Fittings must be positioned parallel to the front and rear of the racks so as to provide good working illumination front and rear of the racks. All light fittings must be installed below any high-level containment, ductwork or other installations so as to avoid shadows. If the lights are controlled by motion sensors the number and position should be such that full room coverage is provided for a single person working at any position or elevation within the room. The minimum number of sensors to provide coverage is 4. The preferred option is manual light switches which must be located adjacent to the entry door; they must not be located to the hinge side of the door opening. Emergency lighting must be provided within the room. 3.8 POWER Cabinet power must be supplied from a building UPS located externally to the comms room. The UPS must be resilient in nature providing 4KVA per occupied or potentially occupied cabinet position. Run time must be a minimum of 30 minutes at full load. Each cabinet footprint must be provided with 2no 16A commando sockets to BSEN each on dedicated circuits, to be protected by 2no 16A Type C MCBs. One commando socket must be fed from the building UPS and the other of the pair must be fed direct from mains (to protect against UPS failure). Each pair of sockets feeding a single cabinet must be fed by a readily accessible 4-pole rotary isolator switch providing simultaneous isolation to both sockets. The isolator switch is to be located on the wall immediately behind each cabinet. The commando sockets must be supplied from a distribution board within the comms room. It is preferred that sockets are located at high-level above the rear of each cabinet and not obstructed by basket, tray work or other services. In addition to the commando sockets, 4no general sockets should be provided to the perimeter of the room to provide general power; these must be provided on a dedicated ring for the comms room from the general building supply. 3.9 UPS If a building UPS is not supplied, then each cabinet must be supplied with a UPS. The requirements are as follows: Capacity of 3300VA On-line, double conversion At least 30 mins runtime at 1000W load 2 C13, 1 C19 Outlets Fitted with a SNMP Management card providing temperature and humidity monitoring. 9

10 The batteries, as supplied must be less than 6 months from date of manufacture. COMMUNICATIONS (COMMS) ROOMS The UPS supply lead must be fitted with a 16A commando plug. The UPS must be installed into the cabinet and connected to one of the provided 16A sockets. The current model recommended by ISS is the Eaton 9PX 3000W RT3U (tower/rack 3U short depth) Part Number 9PX3000IRT3U, must be supplied with Network-MS card POWER DISTRIBUTION Each cabinet must be provided with two power distribution units (PDU). Each PDU must provide 18 C13 and 2 C19 outlets and provide an IP-enabled power meter. The PDU should be zero-u vertically mounted. The current model recommended by ISS is an Eaton EMIB09. Where a UPS is provided within the rack in the comms room, one PDU must be fed from the UPS and the other directly from the mains using the 16A commando socket above the rack. Where the comms room is supplied via a building UPS, then both PDUs must be fed from the 16A commando socket above the rack EARTHING Adjacent to each pair of 16A commando outlets a copper earth bonding bar with a minimum of 4 unused M8 hex-headed bolt attachment points must be provided. Each earth bar must be individually bonded back to the local distribution board with 10mm 2 cable ENVIRONMENTAL Where a building UPS is supplied the comms room environmental conditions must be maintained between 14 C and a maximum 35 C with a humidity range of 15% to 95% non-condensing. Any external ventilation must be filtered to prevent particulate ingress. Passive systems for cooling are preferred. The design of such cooling should be made with discussion and approval from ISS Network Contacts. Where a building UPS cannot be supplied the room will house UPS s containing sealed lead-acid batteries which require controlled environmental conditions and so must be controlled to a minimum temperature of 18 C and a maximum of 24.0 C with a humidity range of 15% % non-condensing. The anticipated heat load per cabinet is estimated to be 2kW. Where UPSs within the comms room are provided duty-only air-conditioning must also be provided ACOUSTICS The room will house equipment which will emit noise. Coordination is required within the design team to mitigate the transference of this noise to surrounding areas. As a guide, the following equipment will be installed within the room: 10

11 Equipment Qty Noise Output (each) Edge Switch 8 per cabinet 53.5 dba Aggregation Switch 2 per comms 58dBA UPS 1 per cabinet 53dBA COMMUNICATIONS (COMMS) ROOMS 3.14 CABINETS Cabinets installed must be Rittal TS IT Cabinet, 800mm wide x 1000mm deep x 42U high with 78% perforated wardrobe doors front and rear with non-self-locking locks. The cabinet must be supplied with the internal earth bonding kit and bar. Cabinets must be installed in a line and bayed together with a divider panel between each cabinet. Side panels at the end of the row must be fitted. All components of the cabinet including doors, rails and side panels must be earth bonded in accordance with the manufacturer s instructions. Each cabinet must be individually earth bonded to the appropriate earth bar (see section 3.11) using 6mm 2 cable. The front pair of rack rails must be positioned to provide 120mm of clearance between the face of the rails and the face of the closed cabinet door. An example cabinet layout is shown on the following page. Individual cabinet layouts must be discussed and agreed with ISS during the detailed design and construction phase. If the last rack to be populated is going to be more than 50% full by the completion of the building project, then an additional rack must be installed in the spare expansion footprint, along with appropriate baying and cable basket. 11

13 4 OPTICAL FIBRE CABLES LANCASTER UNIVERSITY DATA NETWORK PHYSICAL INFRASTRUCTURE SPECIFICATIONS OPTICAL FIBRE CABLES 4.1 GENERAL POINTS Bespoke Fibre Solutions Some projects will require bespoke fibre solutions that may deviate from this specification; check with ISS Network Contacts early on in the project Containment All fibre must be installed into its own dedicated containment. 4.2 CONNECTION OF BUILDINGS TO THE CAMPUS FIBRE NETWORK The Lancaster University campus has a network of duct containing fibre that runs around the perimeter road known as the Halo. Depending on the size, location and purpose of the building, a building may require to be connected to the Halo. Alternatively, the building may connect to an adjacent building that is already connected to the Halo. The decision concerning which of these two options is chosen needs to be taken in early stage discussions with ISS Network Contacts so that appropriate designs can be produced for duct routes into the building Option 1 Direct Connection to Campus Halo Fibre The building will need ductwork that connects to the Halo ductwork (see Ductwork, Main Duct & Subduct sections below). Fibre must then be run to the following locations: Faraday Building LA31 ISS Building B18 As a minimum, the fibre installed must be a hybrid, 96 core OS1 G.652, 24 core OM2 loose tube, 12f per tube internal/external grade cable. The current cable recommended by ISS is Brand Rex HF(96x008+24x050)S120WLU. Final fibre count must be agreed with ISS Network Contacts. One cable will be routed in a clockwise direction around the Halo to get to its destination location; the other will go anti-clockwise. Routes and subduct allocations will be advised by ISS Network Contacts Termination Termination of the fibre must be performed by fusion splicing onto factory-made 600µm LC pigtails. In the Faraday and ISS building locations, the fibre will be terminated into pre-existing Optical Distribution frames (ODF). The contractor must supply an appropriate number of SpliceUK 24f LC splicing cassettes to install into the ODF, (note: cassettes are ordered in right and left-handed orientation. The space allocated for the project in the ODF must be confirmed by ISS Network Contacts so that the correct cassettes can be specified) In the building comms room, a SpliceUK 6U chassis must be installed to terminate the fibre along with an appropriate quantity of 24f LC cassettes. 13

14 OPTICAL FIBRE CABLES Option 2 Link to Adjacent Building The building will connect to an adjacent building specified by ISS (note: this option will only be used for small buildings where a Halo connection is not appropriate). Blown fibre microduct must be installed between the building comms room and an existing comms room in another building identified by ISS. The microduct to be installed is Emtelle FibreFlow 24 LFH x 5/3.5mm tubes (part codes 6513, 6612, 6612L as appropriate for the distance) between the 2 locations. The FibreFlow bundle must be terminated into a suitable enclosure mounted on the wall of the comms rooms, and the required number of individual fibre bundles extended from the enclosure to the fibre tray chassis within the racks using SpiceUK f-tube. The microduct must then be populated with 24f OM4 and 24f G652d fibre as a minimum, but the final fibre count must be agreed with ISS Network Contacts. In the new comms room, a 3U SpliceUK chassis with an appropriate number of 24f LC cassettes must be installed. In the existing comms room, it may be possible to utilise an existing SpliceUK chassis only requiring to provide an appropriate number of 24f LC cassettes, or if insufficient space is available then a new 3U SpliceUK chassis will be required. Termination of the fibre must be performed by fusion splicing onto factory-made 600µm LC pigtails. 4.3 INTERNAL BUILDING FIBRES Where there is more than one comms room within a building, one shall be designated by ISS Network Contacts as primary and the others secondary. Normally, the primary comms will be connected to the Halo (either directly using option 1 or indirectly using option 2 above), then the secondary comms room will connect to the primary comms room using the Emtelle FibreFlow system as described in 4.3 (Option 2) above. In some cases, ISS Network Contacts may request that two comms rooms receive their own separate diverse connections to the Halo. 4.4 DUCTWORK Where the building is required to connect to the Halo infrastructure, then new ductwork will be required, this will comprise of main duct and associated subduct Main Duct The Halo infrastructure runs around the perimeter road and down selected avenues on Campus. ISS Network Contacts will identify an appropriate interconnection point on the Halo for the building to link to. A new section consisting of 2no main ducts will be required from the building to the nominated connection point, this must include any required turning or pulling chambers. The duct provided must be suitable for subducting so care must be taken at any point of change of direction to ensure that the minimum bend radius of the subduct can be satisfied. 14

15 OPTICAL FIBRE CABLES The main duct used in the Halo is Emtelle Solidwall upvc duct 96.5 outside diameter, 90mm inside diameter, colour green. The bends used on this ductwork must be suitable for 4-way subducting, the sharpest bends used must be 22.5 over a length of 700mm, so that the minimum bend radius for the subduct is not exceeded. Only full length proprietary bends suitable for use as part of the ductwork system will be acceptable i.e. used as supplied and not cut or modified. Any ductwork installed must be brushed, and then tested with a dumbbell mandrel with a diameter of 7% less than the main duct inner diameter immediately following installation and prior to subducting. This process must be made available for witness testing by ISS. Any main duct not subducted must be provided with a draw rope. The Halo duct systems, either existing or installed as part of a project are only to be used to carry ISS fibre infrastructure Subduct One of the two main ducts installed to the building must be subducted with 4-way subduct. The subduct used in the Halo is Emtelle 32mm outside diameter, 27mm inside diameter in colours; orange, green, blue, black. Each subduct must be provided with a draw rope. Once installed, all subduct sections must be coupled-through with aluminium (not plastic) screw-on couplers. The part number of the Emtelle aluminium screw-on couplers is 3650M.Unused subducts must be capped. The lowest free main duct must always be subducted first. Any subduct installed must be tested with a dumbbell mandrel with a diameter of 7% less than the subduct inner diameter immediately following installation. This process must be made available for witness testing by ISS Network Contacts. It may be necessary for the project to subduct a section of the main Halo; this requirement must be discussed and agreed with ISS Network Contacts early in project design Access Chambers Any chambers used for pulling or turning must be standard BT F4, F6, or F10 or their carriageway equivalent. Chambers must be constructed of in-situ poured concrete. Pre-cast or plastic chambers are not acceptable. Chamber frames and lids appropriate to the expected traffic loading must be fitted. All duct entries into chambers must be either cast or core-drilled in. Ducts must enter chambers at right angles to the wall. Care should be taken when selecting entry and exit points to a chamber to ensure the minimum bend radius of the subduct within the chamber can be satisfied. A minimum of 100mm clearance must exist between the bottom of the lowest duct and the finished chamber floor. 15

16 OPTICAL FIBRE CABLES When it is necessary to create a chamber onto an existing section of the Halo Infrastructure, it must only be done when that route is agreed with ISS. The works to create that chamber must be coordinated with, and performed by, a contractor approved by ISS to ensure minimal risk to the live services contained within the existing ducts. Chamber plans can be found on the following pages. 16

20 OPTICAL FIBRE CABLES 4.5 LABELLING Where the fibre/microduct/sub-duct passes through a barrier or riser opening, and immediately prior to entry into the ODF, the fibre/sub-duct must be clearly labelled with the A and B end of the fibre with an engraved traffolyte label. This must be black text on yellow background and comply with regulations BS EN for all labels: The splice cassettes in both comms room chassis and Datacentre ODF must be labelled with the source of the fibre and the fibre numbers contained within they tray, fibre numbers must always count-up starting at the rear of the tray: 4.6 FIRE ALARM FIBRES A SpliceUK 2-tube f-tube microduct must be installed from the comms room to the main Gent Vigilon fire alarm panel to allow it to be linked to the fibre network. This must be populated with 8f OM2 fibres. In the comms room, there may be capacity in the newly installed chassis to accommodate a 24f LC tray to terminate the fibre onto; otherwise a new SpliceUK chassis will be required. At the fire alarm end, an appropriate proprietary housing must be used to allow patch leads of a length no longer than 3 metres to be routed to the fire alarm panel. This item will require close coordination with the ISS Network Contacts and all other interested parties so as to meet aesthetic requirements of the building entrance whilst maintaining easy access for future maintainability. The current recommended termination panel to be used inside the proprietary housing adjacent to the Fire Alarm panel is the Optibox4 by Huber & Suhner. 4.7 TESTING AND ACCEPTANCE PROCEDURE In order for fibre optic cables lines to be accepted by ISS, three stages must be completed, with details below: Contractor tests the fibre optic cables Contractor sends test results to ISS Network Contacts Witness testing of fibre optic cables by ISS Network Contacts if required Contractor tests the fibre optic cables Newly installed and spliced optical fibre cable must be fully tested using calibrated test equipment. 20

21 OPTICAL FIBRE CABLES Each individual fibre must be tested with both an OTDR and calibrated light source/power meter (ILM). Testing of each individual fibre must be carried out from both ends of the fibre. For OTDR testing where the fibre length is less than 3km in length the pulse width used for testing must be 3ns or less. High quality fibre patch leads of the correct modal type must be used for all testing, the connectors of which must be cleaned before each insertion with a one-click fibre cleaner. During OTDR testing high quality launch and receive leads of the correct modal type must be used at the appropriate ends of the fibre under test. The connectors on these leads must be cleaned prior to each insertion with a one-click fibre cleaner. Multi mode fibre must be tested at both of 850nm 1300nm. Single mode fibre must be tested at both 1310nm 1550nm. The tabulated results must be presented in a common spreadsheet format and must include as a minimum: Serial number of testers used. Fibre type. Number of connectors. (Normally 2) Number of splices. (Normally 2) Fibre length km (from OTDR measurement). Manufacturers quoted loss figures for each of the test wavelengths as detailed above, db/km. For each wavelength, loss budget for fibre under test (total allowed connector loss + total allowed splice loss+ (measured length in km * manufacturers quoted loss figures for each of the test wavelengths as detailed above, db/km)) For each fibre and each wavelength. Fibre identification (fibre number and type (sm or mm)). ILM loss direction A ILM loss direction B ILM average of loss in direction A and direction B ILM headroom (ILM budget average ILM) Loss at each connector and at each splice from direction A Loss at each connector and at each splice from direction B For each connector loss, the mean average loss in both directions For each splice loss, the mean average loss in both directions Additionally, the OTDR traces must be provided Test Limits At all times the maximum individual splice loss must be less than or equal to 0.250dB. At all times individual connector loss must be less than or equal to 0.50dB and must be repeatable across multiple remove insert cycles. Return loss for single mode connections must be greater than or equal to 26.0dB with a mean average value of 50.0dB. 21

22 OPTICAL FIBRE CABLES Return loss for multi-mode connections must be greater than or equal to 20.0dB with an mean average value of 30.0dB Return loss per splice must be greater than or equal to 40.0dB Contractor sends test results to ISS Network Contacts The results are to be tabulated (example spreadsheet linked below) and supplied to ISS Network Contacts prior to witness testing. Test results, along with in-date calibration certificates, must be ed to A copy of the in-date calibration certificates for each piece of test equipment used must be supplied with the test results. The calibration must have been performed by a manufacturer-approved calibration centre. Test results will not be accepted without an in-date calibration certificate. An example sheet of test results is available at Witness testing by ISS Network Contacts The contractor should be prepared to undertake 100% witness testing of installed lines. Any reduction in this will be at the discretion of ISS Network Contacts. If ISS deem witness testing to be necessary, the contractor will be informed and requested to attend for the witness testing within 2 working days. A time and date will be agreed during this contact. The contractor must supply at least 2 staff to perform witness testing which will be observed by ISS staff. The testing must be undertaken with the contractors test equipment which, whilst it does not have to be the same set used for the original tests, must be in calibration and supplied with valid calibration certificates. 22

23 5 CAT6 CABLING LANCASTER UNIVERSITY DATA NETWORK PHYSICAL INFRASTRUCTURE SPECIFICATIONS CAT6 CABLING The campus standard for data cabling is CAT6, any additional lines or relocations must be CAT6 regardless of any other cabling systems or standards in place. This includes additional telephone sockets, these must now be presented as a CAT6 line with associated RJ45 BT adaptor; no additional BT-style sockets are to be installed. All cabling systems in use must conform to and follow EN : NUMBERS OF DATA LINES IN NEW BUILDINGS AND REFURBISHMENTS ISS Network Contacts must be informed by the project manager of the projected total number of data lines terminating in each comms room, as soon as the number has been finalised, and must be kept updated with any changes throughout the project. Gathering requirements for data line numbers and positions Equipment Requiring Network Connection Printers Wi-Fi Access Points PCs, phones and audio-visual equipment in lecture theatres, seminar/meeting rooms, public spaces.

Contractors must submit detailed cabinet layouts to ISS Network Contacts for written approval prior to the commencement of installation 5.3 PATCH PANELS The patch panels must be one of the listed models in section 5.2 Structured Cabling Systems. Data lines must be terminated to TIA568B standard (fig2), using a cabling system manufacturerapproved tool for the type of panel in use. 24

25 CAT6 CABLING Lines are to be grouped on the patch panels according to the area in the building to which they run, i.e. all lines to room a together, all lines to room b together etc. For each 24 data lines, 1 patch panel will be required. Patch panels must be fully occupied before starting terminations on the next panel up, i.e. no unterminated (empty) ports. No more than 8 lines feeding Wi-Fi data points are to be installed in each pair of adjacent 24 port patch panels. Check with ISS Network Contacts if there is a problem. Patch panels must be laid-out as shown in section 3.12 unless a variation is instructed in writing from ISS. Patch panels must be attached to the rack rails using all metal cage nuts with M6 thread PZ3 machine screws. Washers must NOT be used. A cage nut and bolt must be fitted for each corresponding mounting hole in the patch panel. Patch panels must be correctly aligned within rack U boundaries; they must not cross U boundaries. 5.4 DATA POINTS Where not fully populated the unused module positions must be fitted with half-width (one module) blanking covers. Wiring must be arranged so that expansion to the full capacity of the face plate is not restricted. Self-closing shutters on data point modules must be checked as part of the installation/testing procedure. Any modules with sticking shutters must be replaced and the line re-tested before witness testing. Sufficient depth must be allowed behind the module to prevent crushing or over-bending of the cable as the faceplate is installed. Care must be taken to ensure that the faceplate fixing screws do not impinge upon the cable. The cable must enter the back box or floor box from a direction that minimises cable bending. 25

26 CAT6 CABLING 5.5 INSTALLATION All fixed wiring between patch panel and room outlet must be installed to TIA/EIA568-B.2-1 CAT6 standard. All cable installed must be as per section 5.2 Structured Cabling Systems above. In accordance with CAT6 specification the maximum electrical length of cable between patch panel and data point is 90.0m. During installation the manufacturer s minimum bend radius must be adhered to. The manufacturer s specifications as to whether the cable can be installed by pulling or laying must be followed. Where the manufacturer specifies the cable is suitable for pulling the manufacturer s pulling tension must be adhered to. Where additional cables are to be fitted to an existing patch panel the new cables must be loomed with and follow the route of any existing cables. As the new cables are installed any existing cable fasteners must be removed and replaced by new to prevent the embedding of multiple fasteners within cable bundles. All cable fasteners must be fitted so as not to crush the outer jacket of the cable. All cable ties must have any excess length removed by cutting flush to the body of the ratchet mechanism leaving no sharp edges exposed (see figure 2 below): Figure 2 Within equipment cabinets, cables must be loomed together in groups of 24, all 24 cables must be associated with the same 24 port patch panel. Throughout the horizontal sections of cable routes the cables must be loose-laid. Cable bundles must leave the patch panel in the horizontal plane and be routed through the cabinet so as not to encroach into any equipment space. 26

27 CAT6 CABLING Cable bundles must not me covered with cable sock or similar materials. 5.6 CABLE CONTAINMENT Cable must not be run within the same containment as any power cable at any point. Minimum separation distances within EN50173 and the latest IET wiring regulations (BS7671) must be maintained for any crossing of cabling routes. At all times cables must be supported on top of tray/basket. Cables must not be hung from inverted tray/basket. Metallic cable ties must not be used. Where additional cable containment is required the sizing of the components should be such that at least 50% of the newly installed containment remains free for further cable following the completion of the installation. Where additional tray is installed only hot dipped, post galvanised steel return edge tray of a minimum width of 100mm must be used. All cut edges must be smoothed, no sharp edges are to remain. Lengths of tray must be jointed using appropriate fastenings; e.g. Hex-headed nuts, bolts of the correct length, washers must be used, sharp, cut edges not acceptable. Where additional cable basket is installed only bright zinc plated product of a minimum width of 100mm must be used. Cut ends of basket wire must be either cut flush to the nearest weld point and filed smooth and flush or cut approximately 10mm from the nearest weld point and the cut end covered with a tight fitting PVC or similar protective cap. Where runs of tray/basket change direction proprietary components rather than on site manufactured items must be used. 90 degree bends must be achieved with the use of 2 successive 45 degree bends. Any cable tray/basket supports must not reduce the cable carrying capacity of the tray/basket. In general supports should be external to the cable carrying area of the tray/basket. Where support is via threaded rod this must be M10 BZP steel. The threaded rod must be sleeved over its full length with white 20mm, heavy gauge, high-impact upvc conduit. This protects cable from damage when routing past the threaded rod. Where fitted threaded rod must be cut flush with the end fixing and filed smooth or the ends covered with a tight fitting PVC or similar protective cap. Cable tray/basket must not be used to carry power circuits. However, all sections of tray/basket must be electrically bonded and the whole assembly earthed. Where circular conduit is used for CAT6 cabling, the following maximums for capacity must be observed; 2no CAT6 cables within 20mm conduit, 4no CAT6 cables within 25mm conduit. 5.7 LABELLING Any reference to room number should be the Lancaster University room number as advised by Facilities and not the architectural or construction room number. 27

28 CAT6 CABLING Patch Panel Labelling The patch panel labelling must adhere to the pitch spacing of the panel so that each port label aligns accurately with each port. Labels that do not accurately align with the port or overlap adjacent ports will not be accepted. The label on the patch panel should be of the form (not including < or > characters): <RoomNo> An example for a single label for one port on a patch panel is shown below. The remote end of this port will be in room A23: Figure 3 Each patch panel must be clearly labelled on the left hand side with its correct patch panel number, eg PP Data Point Outlet The label on the outlet must be directly attached to the module, and must take the form <Comms room number>/<rack ID> <Patch Panel No>/<Port No> Where rack ID is the identifier for the rack in the comms room, A,B,C etc. A data point label for Comms room B48, Rack C, patch panel 1, port 21 is shown below. Figure 4 Patch panel number is the number of the patch panel within the identified rack, where each CAT6 patch panel in the rack has a unique identifier, starting at the bottom of the rack with panel number 01, and 28

29 CAT6 CABLING port number is the number of the port on the identified patch panel in the identified rack where the other end of the data line presents Labels - General Labels must be typed or printed, not hand written. Text to be black on a white background. Labels must use the label-mounting locations and not overlap adjacent port areas nor obscure port numbers. 5.8 DATA POINTS FOR WI-FI ACCESS POINTS Wireless networking (Wi-Fi) must be provided in any new building or refurbishment. Aside from major building or refurbishment projects, there are often smaller Wi-Fi deployments to boost signal strength where required. For early-stage building design and budgeting, it should be assumed that there will be one wireless access point for every 90m 2 of open floor area Responsibilities The technical design of the wireless network service in building and refurbishment projects will be done by ISS. This means that the ISS Network Contacts will Annotate floor plans to show the required positions of CAT6 data points for use by Wi-Fi access points Decide which model of Wi-Fi access point is to be deployed Instruct on orientation and positioning of Wi-Fi access points relative to other objects, some of which is documented below and some of which will be undertaken on site during the installation phase. ISS staff will also Undertake procurement of the Wi-Fi access points for use in the project. This procurement is funded by the building project, not by ISS. Configure and install the Wi-Fi access points. These arrangements mean that from the point of view of project managers, electrical engineers and data line installers, installation of Wi-Fi is usually just the installation of specially placed CAT6 data lines, 29

30 CAT6 CABLING as directed by ISS. In some cases, there are additional requirements such as IP-rated housing for the Wi- Fi access points in certain environments. Once the CAT6 data lines for Wi-Fi are tested and accepted by ISS Network Contacts, ISS staff will then mount the wireless access points over the pattress boxes, covering them. The only equipment in view is then the wireless access point Data Line Installation For Wi-Fi For each wireless access point location, a single CAT6 data line must be terminated in a minimum 49mm deep single pattress box e.g. MK8901ALM (surface or flush mounted, facing downward). The front of the pattress box must have at least 150mm clear on all sides, at least 75mm clearance must be available to the front (i.e. below) with no metallic materials in front (i.e. below). Positioning arrangements of data points for Wi-Fi are critical to avoid obstructions to the wireless signal propagation, and to allow staff access to maintain the wireless access points. Discussions with ISS Network Contacts are required in order to determine the most appropriate positioning arrangement in each location. Following are examples of acceptable data line installations Figure 5 Wi-Fi data point before installation of access point 30

Data wiring test equipment must be calibrated and have a current calibration certificate. Marginal or starred passes will not be accepted Contractor sends test results to ISS Network Contacts An electronic copy of the full test results must be supplied to ISS immediately following the testing phase. Test results, along with a copy of the test equipment s calibration certificate, must be submitted by to networking-testresults@lancaster.ac.uk. Once received the results will be reviewed by ISS within a maximum of 5 working days. The test results must be supplied as a spread sheet or.csv file. If Fluke testers are used, then the original.flw results file must also be supplied. These results will be used as the basis for subsequent witness testing to verify the quality of results. 32

33 CAT6 CABLING A copy of the calibration certificate for the test equipment used must also be supplied with the results. The calibration must have been performed by a manufacturer-approved calibration centre. All test equipment must be within a valid calibration period when both testing and witness testing takes place. Test results must contain as a minimum: Make model and serial numbers and valid calibration period of the test equipment used. The velocity factor parameter (NVP) entered into the test equipment. For each line o Overall pass/fail with respect to the CAT6 specification. o Line length in metres. o NEXT (Near end crosstalk) o PSNEXT (power sum near-end crosstalk) o FEXT (Far end crosstalk) o Attenuation o Return loss o ACR (attenuation to crosstalk ratio) Where the pass-margin deviates substantially from the value expected for the line length in question, then further investigations may be undertaken during witness testing. An example sheet of test results is available at Witness testing by ISS Network Contacts The contractor should be prepared to undertake 100% witness testing of installed lines. Any reduction in this will be at the discretion of ISS Network Contacts. If ISS deem witness testing to be necessary, the contractor will be informed and requested to attend for the witness testing within 2 working days. A time and date will be agreed during this contact. The contractor must supply at least 2 staff to perform witness testing which will be observed by ISS staff. The testing must be undertaken with the contractors test equipment which, whilst it does not have to be the same set used for the original tests, must be in calibration and supplied with valid calibration certificates. 33
