Troubleshooting Using the T1600 Chassis and Interface Alarm
Messages
When the Routing Engine detects an alarm condition, it lights
the red or yellow alarm LED on the craft interface as appropriate,
trips the corresponding alarm relay contact on the CIP, and reports
the cause of the alarm in the craft interface LCD. To view a more
detailed description of the alarm cause, issue the show chassis alarms CLI command:
user@host> show chassis alarms
There are two classes of alarm messages:
- Chassis alarms—Indicate a problem with a chassis
component such as the cooling system or power supplies, as described
in Table 1.
- Interface alarms—Indicate a problem with a specific
network interface, as described in Table 2.
In both Table 1 and Table 2, the text in the column labeled
“LCD Message” appears in the LCD. The text in the column
labeled “CLI Message” appears in the output from the show chassis alarms command.
