Chassis Component Alarm Conditions on EX8200 Switches

Purpose
Action
304
The switch supports these alarms:
Chassis alarms indicate a failure on the switch or one of its components. Chassis alarms
are preset and cannot be modified.
System alarms indicate a missing rescue configuration. System alarms are preset and
cannot be modified, although you can configure them to appear automatically in the
J-Web interface display or the CLI display.
Alarm Severity Levels
Alarms on switches have two severity levels:
Major (red)—Indicates a critical situation on the switch that has resulted from one of
the following conditions. A red alarm condition requires immediate action.
One or more hardware components have failed.
One or more hardware components have exceeded temperature thresholds.
An alarm condition configured on an interface has triggered a critical warning.
Minor (yellow or amber)—Indicates a noncritical condition on the switch that, if left
unchecked, might cause an interruption in service or degradation in performance. A
yellow alarm condition requires monitoring or maintenance.
A missing rescue configuration generates a yellow system alarm.

This document provides information on chassis alarm conditions, and how you must
respond when a certain chassis alarm is seen on your switch.
Various conditions related to the chassis components trigger yellow and red alarms. You
cannot configure these conditions. See

You can monitor chassis alarms by watching the ALM chassis status LED and using the
LCD panel to gather information about the alarm. See
Switch" on page 35 and "LCD Panel in an EX8200 Switch" on page
To display switch chassis alarms in the CLI, use the following command

The command output displays the number of alarms currently active, the time when the
alarm began, the severity level, and an alarm description. Note the date and time of an
alarm so that you can correlate it with error messages in the messages system log file.
