Procedures

NOTE:
If a loopback is used to reduce the amount of test equipment needed while
testing 41F-type Gigabit Ethernet OTUs, remove the loopback before
removing the test signal. While the loopback is in place, if a loss of signal
condition is introduced by removing the test signal, a circuit pack failure
may be seen on the pack with the loopback in place. Restoring the signal
may not clear the failure and the circuit pack may require reseating. Upon
circuit pack recovery, enter the Configuration.Update.System command.
Miscellaneous
Discrete Power
Fail Test for Non-
Integrated OLS/
OT Systems The miscellaneous discrete Circuit Pack Fail Alarm is required to turn ON for all
OTUs within a shelf when there is either an A or B supply failure. In addition, each
shelf will have two miscellaneous discrete Power Fail alarms, one for the A power
source and the other for the B power source.
