Hardware Troubleshooting

C.1. Problem

LCD is off

1.Check the power connection on the controller board and LCD panel.

2.Check that a minimum of 128MB SDRAM DIMM is installed.

7-segment LED flashes "F"

1.The DIMM module is not installed yet.

2.The socket plug (loop-back circuits board) for the battery charger connector (JP8) is not installed.

 

Problem

Solution

 

7-segment LED flashes "F"

1.

DIMM module not installed yet.

 

 

 

 

 

2.

Socket plug (loop-back circuits board) for battery

 

 

 

 

 

 

charger connector (JP8) not installed.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

SCSI channel failure detected

1.

Check cable connection

 

upon start-up (SCSI cables

2.

Check ID numbers (must be unique for each device

 

connected)

 

on the same SCSI channel).

 

Message on LCD:

3.

Make sure that SCSI channels are properly

 

 

 

 

 

 

terminated.

 

 

SCSI CHLs fail

 

 

 

 

 

 

 

4.

Check the voltage output of the power supply.

 

 

CHL=x,x,x

 

 

5.

Connect both power connectors

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Initialization failure

1.

Check ID numbers (must be unique for each device

 

 

 

 

 

 

on the same SCSI channel).

 

 

 

 

 

2.

Make sure terminators are properly installed.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Cannot detect SCSI drive

1.

Check drive power connection.

 

 

 

 

 

2.

Check drive SCSI cable connection.

 

 

 

 

 

3.

Check ID numbers (must be unique for each device

 

 

 

 

 

 

on the same SCSI channel).

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Host can not detect the controller

1.

Check host-side SCSI cable connection.

 

 

 

 

 

2.

Check SCSI port to LUN assignment.

 

 

 

 

 

3.

Check logical drive's mapping to LUN.

 

 

 

 

 

4.

If there is no logical unit created, the controller must

 

 

 

 

 

 

be set as a peripheral device.
