Configuring Conditions That Trigger Alarms

For the different types of PICs, you can configure which conditions trigger alarms and whether they trigger a red or yellow alarm. Red alarm conditions light the RED ALARM LED on the router’s craft interface and trigger an audible alarm if one is connected to the contacts on the craft interface. Yellow alarm conditions light the YELLOW ALARM LED on the router’s craft interface and trigger an audible alarm if one is connected to the craft interface.

Note: By default, any failure condition on the integrated-services interface (Adaptive Services PIC) triggers a red alarm.

To configure conditions that trigger alarms and that can occur on any interface of the specified type, include the alarm statement at the [edit chassis] hierarchy level.



[edit chassis]

alarm {



interface-type {

alarm-name (red | yellow | ignore); 
}


}

alarm-name is the name of an alarm.

Table 40 lists the systemwide alarms and the alarms for each interface type.

Chassis Conditions That Trigger Alarms

Various conditions related to the chassis components trigger yellow and red alarms. You cannot configure these conditions. Table 41 through Table 48 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 41 lists the alarms that the chassis components can generate on an M5 or M10 Internet router.

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 50 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.

Table 50: Backup Routing Engine Alarms

Chassis Component	Alarm Condition	Remedy	Alarm Severity
Alternative media	The backup Routing Engine 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 http://www.juniper.net/support/ or call 1-888-314-JTAC (within the United States) or 1-408-745-9500 (from outside the United States).	Yellow
Boot Device	The boot device (CompactFlash or hard disk) is missing in boot list on the backup Routing Engine.	Replace failed backup Routing Engine.	Red
Ethernet	The Ethernet management interface (fxp0) on the backup Routing Engine is down.	Check the interface cable connection. Reboot the system. If the alarm recurs, open a support case using the Case Manager link at http://www.juniper.net/support/ or call 1-888-314-JTAC (within the United States) or 1-408-745-9500 (from outside the United States)	Yellow
FRU Offline	The backup Routing Engine has stopped communicating with the master Routing Engine.	Open a support case using the Case Manager link at http://www.juniper.net/support/ or call 1-888-314-JTAC (within the United States) or 1-408-745-9500 (from outside the United States).	Yellow
Hard Disk	Error in reading or writing hard disk on the backup Routing Engine.	Reformat hard disk and install bootable image. If this fails, replace failed backup Routing Engine.	Yellow
Multibit Memory ECC	The backup Routing Engine reports a multibit ECC error.	Reboot the system with the board reset button on the backup Routing Engine. If the alarm recurs, open a support case using the Case Manager link at www.juniper.net/support/ or call 1-888-314-JTAC (within the United States) or 1-408-745-9500 (from outside the United States)	Yellow

Silencing External Devices

You can manually silence external devices connected to the alarm relay contacts by pressing the alarm cutoff button located on the craft interface front panel. Silencing the device does not remove the alarm messages from the display (if present on the router) or extinguish the alarm LEDs. In addition, new alarms that occur after an external device is silenced reactivate the external device.

Disabling Physical Operation of the Craft Interface

You can disable the physical operation of the craft interface front panel on the routing platform. When you disable the the operation of the craft interface, the buttons on the front panel, such as the alarm cutoff button, no longer function. To disable the craft interface operation, include the craft-lockout statement at the [edit chassis] hierarchy level:



[edit chassis]

craft-lockout;

For more information about how to configure the craft interface, see Configuring Conditions That Trigger Alarms.
