StorageExpress(TM) System: Testing the SCSI ID Switch
STORAGEEXPRESS(TM) SYSTEM: TESTING THE SCSI ID SWITCH
This test is used to determine if the switches on the back of the
peripheral unit are going bad. This may be the cause of a tape drive
not showing up in Central Console even if it is connected or not
initializing on the LED on the CPU unit. It is usually the 2nd tape
drive that exhibits this problem. Bypassing the SCSI ID switch will
solve these problems.
1. Disconnect the SCSI ID cable (the 6 pin connector on the back of
the tape drive).
2. Set switches on the back of the tape drive to the settings for your
drive described below:
