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). See “Port Carrier Power
Supply Replacement Procedures” above.
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 reissue the recycle carrier command.
a. If the recycle passes, then the port carrier power supplies are healthy,
and the problem is with one of the circuit packs. Reinsert the circuit
packs one at a time. If the status LED shows red after reinserting a
circuit pack, then replace the defective circuit pack. If the status LED
still shows red, then remove the amphenol connector on the back of the
slot containing this circuit pack and reissue the recycle carrier
command. If the status LED shows green, then the problem is with one
of the telephones or the wiring to one of the telephones on this slot.
b. If either port carrier power supply still shows a red status LED, then
check for bent pins and cable placement in the affected carrier. There
are failures that can occur on the EPN’s Maintenance circuit pack that
will not be detected by their respective maintenance, but that will cause
many, if not every, environment test to fail. If many environment tests
are failing, the suspect circuit pack, depending on the system
configuration, should be replaced and the test rerun.
PASS
AC-POWERED SYSTEMS
Both OLSs in the tested carrier were found to be healthy by the EPN’s
Maintenance circuit pack. If the status LEDs on both OLSs are not showing
green, then the EPN MAINT circuit pack may have incorrectly reported the
state of the OLSs. Resolve any alarms on these MOs.
DC-POWERED SYSTEMS
Both power supplies in the tested port carrier were found to be healthy by the
EPN’s Maintenance circuit pack. If the status LEDs on both power supplies are
not showing green, then the MAINT circuit pack may have incorrectly reported
the state of the power supplies. Resolve any alarms on these MOs.
