STATUS

Recommended

The power module shall have a minimum MTBF at continuous operation of 1) 50,000 hours at 100% load and 45 °C, as calculated by Bellcore RPP, or 2) 100,000 hours demonstrated at 100% load and 50 °C.

The power cage shall have a minimum MTBF at continuous operation of 1) 200,000 hours at 100% load and 45 °C, as calculated by Bellcore RPP, or 2) 400,000 hours demonstrated at 100% load and 50 °C

STATUS

Recommended

The power supply must comply with all regulatory requirements for its intended geographical market. Depending on the chosen market, regulatory requirements may vary. Although a power supply can be designed for worldwide compliance, there may be cost factors that drive different versions of supplies for different geographically targeted markets.

This specification requires that the power supply meet all regulatory requirements for the intended market at the time of manufacturing. Typically this includes:

UL

CSA

A Nordic CENELEC

TUV

VDE

CISPR Class B

FCC Class B

The power supply, when installed in the system, shall meet immunity requirements specified in EN55024. Specific tests are to be EN61000-4-2 ,-3, -4, -5, -6, -8, -11, EN61000-3-2, -3, and JEIDI MITI standard. The power supply must maintain normal performance within specified limits. This testing must be completed by the system EMI engineer. Conformance must be designated with the European Union CE Marking. Specific immunity level requirements are left to customer requirements.
