FAIL 

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.
