2.7.329 PWR-FAIL-RET-A
The Equipment Power Failure at Connector B alarm occurs when there is no power supply from the main
power connector to the equipment. This alarm occurs on the electrical interface assemblies (EIA),
15454_MRC-12 Multirate card, MRC-2.5G-4 Multirate card, OC192SR1/STM64IO Short Reach and
OC192/STM64 Any Reach cards (also known as OC192-XFP in CTC), OC12 IR/STM4 SH 1310-4 card,
OC3 IR/STM1 SH 1310-8 card or TCC2/TCC2P.
Warning
The power supply circuitry for the equipment can constitute an energy hazard. Before you install or
replace the equipment, remove all jewelry (including rings, necklaces, and watches). Metal objects
can come into contact with exposed power supply wiring or circuitry inside the DSLAM equipment.
This could cause the metal objects to heat up and cause serious burns or weld the metal object to the
equipment.
