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, then 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, then
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. Use 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, one port carrier power supply, or both, in the tested
carrier is defective. If only one port carrier power supply is defective,
then 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), then replace the defective power supplies).
4. If the replaced port carrier power supply(s) still do not operate properly,
then 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.
