Markings: Sixnet Product Certification Quick Reference List Below are some of the standard and compliance ratings you may see on a SIXNET product. All products sold in Europe must have the CE mark. This means the products meet the appropriate directives. At this time only the EMC Directive (emissions and immunity) and Low Voltage Directive (safety) apply. FCC Part 15: This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. FCC Part 68: Complies with Part 68 of FCC rules: Reg. #####; Ringer Equiv. #.#B; Jack (USOC) RJ11 This is the symbol for Det Norske Veritas. Though most of SIXNET products have been tested for DNV compliance, SIXNET doesn t currently put this symbol directly on any products. This is the UL Listed mark. The C and US means that the product has been tested to both USA and Canada standards. SIXNET applies this mark to products that have been certified UL1604 and UL508. This is the UL Recognized mark. The C (and optionally a US ) means that the product has been tested to both USA and Canada standards. SIXNET applies this mark to products that have been certified for UL508 only. This is the A-tick mark. All information technology equipment (telcom devices) must meet the AS/NZS 3548 standard to be sold in Australia or New Zealand. SIXNET applies this mark to modem products. This is the required Industry Canada mark for telecommunication products. SIXNET applies this only to modem products to indicate that they meet CS-03, the Canadian version of FCC Part 68. This is the CSA mark. SIXNET doesn t put this on any products. SIXNET gets CSA certification through UL and puts the CUL mark (see above) on the products.

MTBF Data for SIXNET Hardware Sixnet Product Certification Quick Reference List GreenMatic SIXNET calculates the actual installed experience of our customers in calculating the Mean Time Between Failure (MTBF) data we publish. We use a conservative estimate of only 70% of units shipped being in service and a usage per day of 12 hours. There are several methods to calculate MTBF. Most often manufacturers quote theoretical calculations that are based upon statistics computed about the components used in the product. We have chosen instead to report actual results, which are gathered from our ISO9001 traceable shipments and return/repair records. MTBF Calculation: First, we determine the average number of units being installed per month (A). Second, we determine the number of months that the unit has been shipping (B). We then can calculate the total number of "unit months" that the unit has been in the field (C). ((A x 1) + (A x 2) + + (A x B)) = C (total number of unit months in the field) (Note: For a twelve-month period, you would multiply 78 times the average number of units installed per month.) Next, we assume an installation rate of 70% of what we shipped and 12 hours operation per day on the average. From this we can calculate the total number of "unit operating hours" (D) as follows: C (from above) x 70% x 12 hours/day x 30 days/month = D (total number of unit operating hours) Finally, to get the MTBF we divide the total number of unit operating hours by the number of applicable failures. An applicable failure is one that cannot be attributed to misuse (i.e. over-voltage, forklift impalement, etc.) or Mother Nature (i.e. lightning, flooding, etc.). (Total number of unit operating hours) / (number of chargeable failures) = MTBF MTBF Data: (last updated 05/2002) Product Units Shipped (1 st year) Average Units / month (A) Total Unit Months (A x 78) Total Unit Hours (A x 78 x.7 x 12 x 30) Applicable Failures MTBF (see notes) SixTRAK I/O 4,000 333 25,974 6,545,448 9 727,272 SixTRAK Gateways & 660 55 4,290 1,081,080 4 270,270 VersaTRAK RTUs Industrial Modems 2,840 236 18,408 4,638,816 9 515,424 RemoteTRAK I/O, EtherTRAK I/O, & Modbus Gateways 1,800 150 11,700 2,948,400 5 589,680 Ethernet Switches 1,715 143 11,154 2,810,808 4 702,702 SiteTRAK and all IPm products Too New. Not enough data yet. Estimated MTBF to be similar to legacy SixTRAK Gateways & VersaTRAK RTUs. Notes: These MTBF numbers are based on data for the first year of production for each product group. For SIXTRAK I/O, the MTBF can be broken down such that for a system with 20 modules, there is only a 1 in 4 likelihood that you will have a single failure in 4 years.
