Chassis Alarm Messages on a QFX3500 Device
Chassis alarms indicate a failure on the device or one of its components. Chassis alarms
are preset and cannot be modified.
Thechassis alarm message count is displayed on the LCD panel on the frontof the device.
To view the chassis alarm message text remotely, use the show chassis lcd CLI command.
Chassis alarms on QFX3500 devices have two severity levels:
•
Major (red)—Indicates a critical situation on the device that has resulted from one of
the conditions described in Table 88 on page 443. A red alarm condition requires
immediate action.
•
Minor (yellow or amber)—Indicates a noncritical condition on the device that, if left
unchecked, might cause an interruption in service or degradation in performance. A
yellow alarm condition requires monitoring or maintenance.
