JUNOS Software with Enhanced Services Hardware Guide

Table 47: Chassis Alarm Conditions and Corrective Actions

Component	Alarm Conditions
Alternative boot media	The Services Router boots from
	an alternative boot device.

PIM	A PIM has failed.
	When a PIM fails, it attempts
	to reboot. If the Routing Engine
	detects that a PIM is rebooting
	too often, it shuts down the
	PIM.

Corrective Action	Alarm Severity
Typically, the router boots from the	Yellow (minor)
internal compact flash. If you
configured your router to boot from
an alternative boot device, ignore this
alarm condition.
If you did not configure the router to
boot from an alternative boot device,
contact JTAC. (See “Requesting
Technical Support” on page xxii.)
Replace the failed PIM. (See	Red (major)
“Replacing a PIM” on page 120)

Routing Engine	An error occurred during the
	process of reading or writing
	compact flash.

Reformat the compact flash and	Yellow (minor)
install a bootable image. (See the
JUNOS Software Administration Guide.)
If this remedy fails, you must replace
the failed Routing Engine. To contact
JTAC, see “Requesting Technical
Support” on page xxii.

Routing Engine temperature is	■	Check the room temperature.	Yellow (minor)
too warm.		(See “Router Environmental
		Tolerances” on page 66.)
	■	Check the air flow. (See “General
		Site Guidelines” on page 63.)
	■	Check the fans. If you must
		replace a fan or the Routing
		Engine, contact JTAC. (See
		“Requesting Technical
		Support” on page xxii.)
	■	If the router has an air filter,
		check the filter and replace it if
		it appears clogged. (See
		“Replacing Air Filters on J2350
		Routers” on page 153or
		“Replacing Air Filters on J4350
		and J6350 Routers” on page 154.)
Routing Engine fan has failed.	Replace the failed fan. To contact		Red (major)
