Description / Recommendation
4. If the replaced OLS(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 OLS from operating properly. Unseat every circuit pack in the
carrier, and enter recycle carrier.
a. If the recycle passes, the OLSs 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,
replace the defective circuit pack. If the status LED still shows
red, remove the amphenol connector on the back of the slot
containing this circuit pack and enter recycle carrier. If the
status LED shows green, the problem is with one of the
telephones or the wiring to one of the telephones on this slot.
b. If either OLS still shows a red status LED, 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.
