critical pack.

Drive Fault LEDs

When amber, the Drive Fault LEDs on back of the cabinet door opposite the drive slots
indicate the disk drive installed in that slot failed.

Power-On Self Test

Immediately upon power on, the InterRAID-8e disk array performs the Power-On Self Test
(POST). If POST does not detect a failure, all LEDs light steady green and the alarm sounds
one short beep. If POST detects a failure, a message displays on the system monitor. The
failures do not compromise the data integrity of the disk drives.
NOTE You can view the POST failures from the Information Control Panel (Chapter 4). If a failure
occurs, the system monitor pauses momentarily, displays the failure, and then continues with
POST. To view the results, select Hardware Menu at the Main Menu and choose POST
Results.

Microprocessor Failures

If POST detects a microprocessor failure, one of the following messages displays on the
system monitor.
RAM Read/Write
ROM Checksum
Register Read/Write Failures
If any of these failures occurs, the channel mode LED blinks amber eight times and the
alarm sounds eight beeps. Then, the channel mode LED changes to steady green and the
system attempts to resume normal operation. If the failures occur consistently, return the
cabinet to Intergraph Computer Systems for repair. Contact the Customer Response Center
at 1-800-633-7248.
