7. TROUBLE SHOOTING GUIDE
The following is a list of possible error indicators or messages, what they
indicate, and possible solutions to the source problem. If no solution is found,
contact the factory for further assistance.
7.1 Error Blink Codes -
If the red LED issues a repeating blink code (accompanied by the drive not
responding to SCSI commands), this indicates a hard error condition as listed
in the table below. Contact the Memtech factory for repair service.
Number of Blinks Error
2 ROM Firmware Checksum error
3 ASIC initialization error
4 SRAM Test failed
5 Remap Table error
6 SCSI controller error
7 Flash/Data Path error
7.2 Warning Blink Codes –
The red LED is also used to indicate a number of warning conditions. If a
warning condition is encountered, the red LED will issue the number of
blinks indicated below a single time, then continue the power-up procedure.
Please note that the warning condition is also entered after each SCSI
reset, so the blink code may be issued several times during power-up at
irregular intervals. Again, contact the Memtech factory for service or repair.
Number of Blinks Error
1 No Flash memory
2 Invalid Remap Table
3 Remap Table disabled (E7 shorted)
7.3 Red LED on steady at power-up-
The red LED will come on when the remap table becomes full. One or more
memory devices have exceeded their useful life. Contact Memtech repair
department for repair or upgrade options.
7.4 Unit does not respond to SCSI commands -
If the unit passes power-up diagnostics, but does not respond to SCSI
commands, there may be a SCSI ID contention among the SCSI bus units.
Make sure that every SCSI ID used on the bus is different. See section 5 to
find out how to change the SCSI ID of the unit.
Note: Status and Sense Error Codes are available in the Reference
Manual.
