VMA-series Memory Array Installation and Service Guide

Understanding Memory Array Alarms
The Memory Array provides you with key tools for identifying and interpreting
raised alarms.
Alarms are indicated by the state of the Alarm LED on the front of the
Memory Array chassis.
Information about an active alarm may then be viewed by running the
show
system alarm
command or show system message command.
This appendix provides information about how to clear these alarms when they
occur.
Interpreting Alarm LEDs
The current status of the Memory Array system may be indicated by the activity
of the Alarm LED on the front of the chassis. The Alarm LED is red.
The Alarm LED identifies the occurrence and severity of an error by its state: no
light, a steady light, or a flashing light.
Many alarms occur during bootup and automatically clear as soon as the system
stabilizes. For example, the Data Plane Unavailable alarm frequently occurs
Figure C.1 Front System Status LEDs
No Light No alarm.
Steady Light A service-affecting alarm has occurred. Service-
affecting alarms are alarms which interrupt
traffic and indicate that the data plane is either
severely impacted or completely disabled.
Flashing Light A non-service affecting error has occurred. Non-
service affecting alarms are alarms which call
attention to errors that do not affect data traffic
on the system.
