Chassis Conditions That Trigger Alarms

Various conditions related to the chassis components trigger yellow and red alarms. You cannot configure these conditions. Table 45 through Table 52 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.

Table 45 lists the alarms that the chassis components can generate on an M5 or M10 Internet router.
