RAM Checksum Failure
If POST detects a firmware failure, the following message displays.
RAM Checksum
The channel mode LED alternately blink s green and amber indefinitely. This indicates
corrupted firmware stored in non-volatile RAM. Intergraph Computer Systems must load
new firmware to correct the failure. Call the Customer Response Center at 1-800-633-7248
for support.
SCSI Bus Access Failure
If the POST detects a failure on the InterRAID-8e disk array, the following message
displays:
SCSI Bus Access Failure
The channel mode LED blinks amber four times and the alarm sounds four beeps. Either the
SCSI controller failed to respond to a reset command or another device has control of the
SCSI bus. After the alarm sounds, the microprocessor attempts to initialize the SCSI
controller. Normal operations will be impossible while the SCSI controller remains
unresponsive.
Power cycling the cabinet (turning the cabinet off, waiting 30 seconds, then powering on
again) may resolve the failure. Next, try reseating cables and RAID disk drives. The cabinet
requires service if this failure persists. Contact the Customer Response Center at 1-800-633-
7248.
NOTE
The InterRAID-8e disk array will not respond to the RAID controller firmware if a SCSI Bus
Access failure occurs.
Hardware and Software Failures
This section contains some miscellaneous InterRAID-8e cabinet and system related failures
encountered and solved by Intergraph Computer Systems.
