Chassis Conditions That Trigger Alarms

Various conditions related to the chassis components trigger yellow and red alarms. You cannot configure these conditions. Table 38 through Chassis Components Alarm Conditions on an M5 or M10 Router list the alarms that the chassis components can generate. For information about chassis alarms for J-series Services Routers, see the J-series Services Router Administration Guide. For information about chassis alarms for the TX Matrix platform, see the TX Matrix Platform Hardware Guide.

Backup Routing Engine Alarms

For routers with master and backup Routing Engines, a master Routing Engine can generate alarms for events that occur on a backup Routing Engine. Table 46 lists chassis alarms generated for a backup Routing Engine.

Note: Because the failure occurs on the backup Routing Engine, alarm severity for some events (such as Ethernet interface failures) is yellow instead of red.

Note: For information about configuring redundant Routing Engines, see the JUNOS High Availability Configuration Guide.
