Procedure 10.24: REPLACE SCSI DISK MODULE
OVERVIEW
This procedure contains information for replacing Small Computer System Interface (SCSI) Disk Unit Package
(DUP) Subunits.
CAUTION 1:
Wear a properly grounded wrist strap throughout this procedure as electrostatic discharge
may damage the disk module.
CAUTION 2:
Touching exposed circuit elements may damage circuits.
PROCEDURE
1.
Remove two screws from each side and one screw from the top (rear center) of DUP.
2.
Slide cover assembly forward to clear switches and gently lift from DUP chassis. There is a cable tie
restraining the ID cable to the CGG2 power supply board. This cable tie restrains the ID cable and power
cable from being damaged when removing the cover and keeps them away from the fan. (See Figure
10.24-6 .) If the cover is to be completely removed from the DUP, the cable tie must be cut.
3.
To replace:
(a)
Disk Module, continue with Step 4.
(b)
Power Supply (CGG2), go to Step 11.
(c)
Power Switch (CGG1), go to Step 16.
(d)
Fan, go to Step 27.
4.
To replace the Disk Module, disconnect the cabling as follows from the rear of the Disk Module (refer to
Figures 10.24-1 through 10.24-4 ):
SCSI bus cable ED-3T053-40, G6
