Alarm
|
Signal alerting you to conditions that might prevent
normal operation. LEDs are the alarm indicators on the device. Blinking
amber LEDs indicate yellow alarm conditions for chassis components.
|
Alarm condition
|
Failure event that triggers an alarm.
|
Alarm severity levels
|
Seriousness of the alarm. The level of severity can be
either major (red) or minor (yellow).
Major (red)—Indicates a critical situation on the
device that has resulted from one of the following conditions. A red
alarm condition requires immediate action.
One or more hardware components have failed.
One or more hardware components have exceeded temperature
thresholds.
An alarm condition configured on an interface has triggered
a critical warning.
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. For example, a missing rescue
configuration generates a yellow system alarm.

Alarm types
|
Alarms include the following types:
Chassis alarm—Predefined alarm triggered by a physical
condition on the device such as a power supply failure or excessive
component temperature.
Interface alarm—Alarm you configure to alert you
when an interface link is down. Applies to ethernet, fibre-channel, and management-ethernet interfaces.
You can configure a red (major) or yellow (minor) alarm for the link-down
condition, or have the condition ignored.
System alarm—Predefined alarm that might be triggered
by a missing rescue configuration, failure to install a license for
a licensed software feature, or high disk usage.
