CARR-POW (Carrier Power Supply)
Issue 1 June 2005 787
FAIL
(cont’d)
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 enter recycle carrier. 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 PN’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 PN’s
Maintenance circuit pack. If the status LEDs on both OLSs are not showing
green, then the PN’s 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 PN’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.
