| CLASS OF CHANGE: | INFORMATIONAL | |
| REASON FOR CHANGE: | HEX STAND OFF WRONG LENGTH |
Reason for change
1. The length of the
hex standoff, used to secure the single-ended and differential SCSI daughter cards
to the SCSI host
adapter on the baseboard is too long. This causes improper seating of the pga
socket to the
SCSI host adaptor. The modification replaces the standoff with a shorter version which
fixes this
problem.
2. A modification kit is required and must be obtained through the service centre manager.
Fro kit 603-5006525 contains the following:
Quantity part number descrition
2 150-0019580 standoff-hex
2 097-0414764 screw-self locking, m3 x 5
Authority for ordering 15-fro-0184
(tech serv ref 02/8/1)
(cssb 94-0057-1)

3. Note: follow proper esd precautionary procedures when installing this change.
4. Ensure the customer has two verified filesaves.
5.1 have the user perform the necessary procedures to shutdown the system in an orderly manner.
5.2 power off the system.
5.3 remove the side panel. This is
accomplished by removing the two thumb screws located on the back
of the system and pushing up
on the release in the inside of the drive bay door.
5.4 detach the SCSI daughter card from the base board (one screw).
5.5 re-attach the daughter card to the board
using the screw and hex standoff provided in the field retrofit kit.
Note that the kit contains two sets
of screws and standoffs but only one set is needed.
5.6 re-assemble the cabinet.
6 Testing
Boot diagnostics to verify the SCSI devices attached to the daughter card are recognised.
7 recording action
Attach a modification label to the daughter pcb if not already fitted and strike through but do no obliterate 2.
Complete all other relevant documentation.
