Firmware Error Conditions
NOTE:
None of the following error conditions will compromise the data
integrity on the CR8e drives.
Any of these failures listed below will generate the following: Channel Mode LED
blinks amber eight times and the alarm will sound eight tones. After the tones
have sounded the Channel Mode LED will change to green and normal operations
will be attempted. These error conditions indicate that the LEDs and alarm
functions may not be reliable.
RAM Read/Write Failure - This error condition indicates that one or more
bytes of the microprocessor RAM failed a write/read test.
ROM Checksum Failure - This error condition indicates that the
microprocessor ROM failed to generate the proper checksum.
Register Read/Write Failure - This err or condition indicates that one or mor e
of the microprocessor’s registers have become defective.
If the errors occur constantly, the CR8e needs to be serviced. Contact nStor
Technical Support.

RAM Checksum Failure

If this error condition occurs, the Channel Mode LED will alternately blink green
and amber indefinitely. This indicates that the firmware stored in the non-volatile
RAM has become corrupted and new firmware data will need to be downloaded
from the SCSI bus to correct this problem. Contact nStor Technical Support.

SCSI Bus Access Failure

If this error condition occurs, the Channel Mode LED will blink amber four times
and the speaker will sound four tones. This indicates that either the SCSI
controller failed to respond to a reset command or another device has control of
the SCSI bus.
Note that this may be caused by other devices having control of the bus at the
time the CR8e is powered ON. After the tones have sounded, there will be a two
second delay, and the microprocessor will again attempt to initialize the SCSI
controller. Turning the system OFF then ON again may help resolve this
condition. Normal operations will be impossible while the SCSI controller
remains unresponsive.
