Nortel Meridian 1 Option 11C Planning And Installation Manual page 159

Incorrectly connected fiber optic cables may cause the following
problems:
– a series of repetitive fault indicating messages
– a complete failure of the expansion cabinet.
If fault indicating messages appear, check the fiber optic cable
connections.
Since messages are stored in a buffer, they may continue to be
displayed until the buffer is empty. After checking the cable
connections, wait a couple of minutes for the messages to stop.
