Understanding Alarm Types and Severity Levels on EX Series Switches
NOTE: This topic applies only to the J-Web Application package.
Alarms alert you to conditions that might prevent normal operation of the switch. Before
monitoring alarms on a Juniper Networks EX Series Ethernet switch, become familiar
with the terms defined in Table 57 on page 211.
Table 57: Alarm Terms
DefinitionTerm
Signal alerting you to conditions that might prevent normal operation. On a switch, the alarm
signal is the ALM LED lit on the front of the chassis.
alarm
Failure event that triggers an alarm.alarm condition
Seriousness of the alarm. If the Alarm (ALM) LED is red, this indicates a major alarm. If the Alarm
LED is yellow, this indicates a minor alarm. If the Alarm LED is unlit, there is no alarm or the switch
is halted.
alarm severity
Preset alarm triggered by a physical condition on the switch such as a power supply failure,
excessive component temperature, or media failure.
chassis alarm
Preset alarm triggered by a missing rescue configuration or failure to install a license for a licensed
software feature.
NOTE: On EX6200 switches, a system alarm can be triggered by an internal link error.
