INU/INUe LEDs
Table 2-1 summarizes INU/INUe LED behavior. Empty cells in this table
indicate that the associated LED state is not used.
Table 2-1.
INU/INUe LED Alarm Table
The event used to trigger an LED is generally at a higher (summary) hierarchy
level than that available within the CT Alarms screen. For example, an NCC
status alarm can be triggered by a component failure, but to get detail on what
component failed, recourse to CT is required.
One or multiple alarms may trigger an LED. For example, an NCC status alarm
can be triggered by a component failure,
or power supply failure, or TDM clock
failure.
Table 2-2 maps LED alarm indications for INU/INUe plug-ins against possible
causes and recommended actions.
• Where recommended actions states CT should be used to see alarm details,
refer to CT Alarms on page 2-16.
