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, then 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,
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 OLS 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.
