Configure 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, or are ignored. 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.

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 18 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 19 lists the alarms that the chassis components can generate.

Table 19: Chassis Component Alarm Conditions

Chassis Component	Alarm Condition	Alarm Severity
Alternative Media	Router boots from alternate boot device. For more information about alternate boot devices, see Boot Devices.	Yellow
Fans	One fan has been removed from the chassis.	Yellow
	Two or more fans have been removed from the chassis.	Red
	One fan in the chassis is installed but not spinning.	Red
Power supplies	A power supply has been removed from the chassis.	Yellow
	A power supply has failed. If both power supplies fail, the router shuts down and the software might report the failures in the syslog file.	Red
Temperature	Chassis temperature has exceeded 54 degrees Centigrade and the fans have been turned on to full speed.	Yellow
	Chassis temperature has exceeded 75 degrees Centigrade and the router has been shut down.	Red
	The temperature sensor has failed.	Red
SCB/SSB/FEB/SFM	The control board (SCB, SSB, FEB, or SFM, depending on model) has failed. If this occurs, the board attempts to reboot.	Red
FPC	An FPC has failed. If this occurs, the FPC attempts to reboot. If the SCB sees that an FPC is rebooting too often, it shuts down the FPC.	Red
Craft interface	The craft interface has failed.	Red
Hot swapping	Too many hot-swap interrupts are occurring. This message generally indicates that a hardware component that plugs into the router's backplane from the front (generally, an FPC) is broken.	Red
