Chassis Conditions That Trigger Alarms

Various conditions related to the chassis components trigger yellow and red alarms. You cannot configure these conditions. Table 1 through Chassis Component Alarm Conditions on M5 and M10 Routers 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 router, see the TX Matrix Router Hardware Guide. For information about chassis alarms for the TX Matrix Plus router, see the TX Matrix Plus Router Hardware Guide

Chassis Component Alarm Conditions on TX Matrix and TX Matrix Plus Routers

For information about chassis component alarms on the TX Matrix and TX Matrix Plus routers, see the TX Matrix Router Hardware Guide and the TX Matrix Plus Router Hardware Guide, respectively.

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 9 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.
