Configuring and Monitoring Alarms

	Alarms on a J-series Services Router alert you to conditions on a network interface,
	on the router chassis, or in the system software that might prevent the router from
	operating normally. You can set the conditions that trigger alarms on an interface.
	Chassis and system alarm conditions are preset.
	An active alarm lights the ALARM LED on the front panel of the router. You can
	monitor active alarms from the J-Web interface or the CLI.
	This chapter contains the following topics. For more information about alarms, see
	the JUNOS System Basics Configuration Guide.
