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 EX Series Switches” on page 637.
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 “Checking Active
Alarms with the J-Web Interface” on page 652.
Table 122 on page 653 lists some of the chassis alarms that an EX8200 switch can generate.
