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 46 describes alarms that can occur for a chassis component such as the Routing Engine or a Physical Interface Module (PIM).

Alternative boot media |
The Services Router boots from an alternative boot device. |
Typically, the router boots from the primary compact flash disk. If you configured your router to boot from an alternative boot device, ignore this alarm condition. If you did not configure the router to boot from an alternative boot device, contact JTAC. (See Requesting Support.) |
Yellow (minor) |
|
PIM |
A PIM has failed. When a PIM fails, it attempts to reboot. If the Routing Engine detects that a PIM is rebooting too often, it shuts down the PIM. |
Replace the failed PIM. (See Replacing a PIM.) |
Red (major) |
|
Routing Engine |
An error occurred during the process of reading or writing compact flash. |
Reformat the compact flash and install a bootable image. (See the J-series Services Router Administration Guide.) If this remedy fails, you must replace the failed Routing Engine. To contact JTAC, see Requesting Support. |
