FAIL DC-POWERED SYSTEMS
There is a problem with one or both port carrier power supplies on the
tested carrier.
1. For each port carrier power supply that has every status LED OFF,
check the DC input to the port carrier power supply at the port carrier
power supply outlet. If there is no DC, check the appropriate circuit
breakers for the affected port carrier power supply. If the circuit
breaker has tripped, reset the circuit breaker. If the circuit breaker
trips again or if DC is absent at the port carrier’s power supply outlet,
there is probably a power wiring problem in the cabinet.
2. At this point, DC should be present at the port carrier power supply
outlet. Enter recycle carrier UUC, where UUC is the
appropriate cabinet and carrier, to attempt to bring back the port
carrier power supplies for this carrier. If the test passes, the trouble is
cleared. If the test does not pass, either one port carrier power supply
or both in the tested carrier is defective. If only one port carrier power
supply is defective, the status LEDs on the healthy port carrier power
supply will light green for a moment. When the recycle test
determines that both port carrier power supplies are defective, the
software will turn off power to both the good and defective port carrier
power supplies. This will cause the status LED(s) on the good port
carrier power supply to light red.
3. Unplug both port carrier power supplies, and wait approximately
1-minute to allow the power supplies to cool down. Plug in the power
supplies. If either power supply is operating properly (the status LEDs
show green), replace the defective power supplies).
4. If the replaced port carrier power supply(s) still do not operate
properly, a circuit pack or a defective telephone connected to a circuit
pack in the affected carrier could be causing an electrical load that is
preventing the power supply from operating properly. Unseat every
circuit pack in the carrier, and enter recycle carrier.
