Failure Detection and Troubleshoot-ing Guidelines

Failure Indicators

When a failure occurs on the array, an audible alarm sounds, if enabled, and the display/operation panel reports the nature of the failure condition.

Audible Alarm

To turn off the audible alarm, press any key on the display/operation panel (except RESET). Write down any error codes that are displayed. Pressing a key will cause the display to change to a different message.

Error/Failure Messages

The display/operation panel shows error codes and failure messages that direct you to the source of failure. If there are no failures, the panel will read 21/,1( (or assigned array name) 67$786￿2..
