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 "Understand Alarm Types and Severity Levels on EX Series Switches" on page 299.
Action
You can monitor chassis alarms by watching the ALM chassis status LED and using the LCD panel to gather
information about the alarm. See Chassis Status LEDs in an EX8200 Switch and LCD Panel in an EX8200
Switch.
To display switch chassis alarms in the CLI, use the following command
user@host> show chassis alarms
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.
You can also monitor chassis alarms using the J-Web interface. See "Check Active Alarms with the J-Web
Interface" on page 311.
Table 89 on page 302 lists some of the chassis alarms that an EX8200 switch can generate.
