Power-On Self Test
Immediately upon power on, the InterRAID 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. 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 for repair. Contact the Customer Response Center at 1-800-633-7248.
