    Chassis Conditions That Trigger Alarms

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

    Chassis Component Alarm Conditions on M5 and M10 Routers

    Table 1 lists the alarms that the chassis components can generate on M5 and M10 routers.

    Alarm Condition

    Remedy

    Alarm Severity

    Alternative media

    The router boots from an alternate boot device, the hard disk. The CompactFlash card is typically the primary boot device. The Routing Engine boots from the hard disk when the primary boot device fails.

    Open a support case using the Case Manager link at

    www.juniper.net/

    or call 1-888-314-JTAC (within the United States) or 1-408-745-9500 (from outside the United States).
