Chassis Alarm Conditions
You can monitor alarms to troubleshoot hardware problems on a Services Router.
Alarms alert you to conditions on the router chassis, or in the system software that
might prevent the router from operating normally. You can monitor active alarms
from the J-Web interface or the CLI.
Services Router alarms warn you about conditions that can prevent the router from
operating normally. Chassis and system alarm conditions are preset. When the
Routing Engine detects an alarm condition, it lights the ALARM LED on the front
panel. When the condition is corrected, the light turns off.
To view a more detailed description of the alarm cause, issue the show chassis alarms
CLI command:
user@host> show chassis alarms
Table 70 on page 209 describes alarms that can occur for a chassis component such
as the Routing Engine or a Physical Interface Module (PIM).
