This document provides information on chassis alarm conditions, and how you should
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 "Understanding Alarm Types and Severity Levels
on J-EX Series Switches" on page 533.
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 a J-EX8200
Switch and LCD Panel in a J-EX8200 Switch.
To display switch chassis alarms in the CLI, use the following command
show chassis alarms
user@host>
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 "Checking Active
Alarms with the J-Web Interface" on page 544.
Table 77 on page 545 lists some of the chassis alarms that a J-EX8200 switch can generate.
