Chassis Alarm Conditions and Corrective Actions

Alternative boot media

The Services Router boots from an alternative boot device.

Typically, the router boots from the primary compact flash disk. 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 Support.)

Yellow (minor)

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.

Replace the failed PIM. (See the Getting Started Guide for your router.)

Red (major)

Routing Engine

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

Reformat the compact flash and install a bootable image. (See Performing Software Upgrades and Reboots.)

If this remedy fails, you must replace the failed Routing Engine. To contact JTAC, see Requesting Support.

Yellow (minor)

Routing Engine temperature is too warm.

• Check the room temperature. (See the Getting Started Guide for your router.)
• Check the air flow. (See the Getting Started Guide for your router.)
• Check the fans. (See the Getting Started Guide for your router.) If you must replace a fan or the Routing Engine, contact JTAC. (See Requesting Support.)
• If the router has an air filter, check the air filter and replace it if it appears clogged. (See the Getting Started Guide for your router.)

Yellow (minor)

Routing Engine fan has failed.

Replace the failed fan. To contact JTAC, see Requesting Support.
