14-4 SCSI Crossover circuit pack (NT6M93xx) - Turbo only
Procedure 14-1
Replacing the SCSI XOVR circuit pack (NT6M93AA or NT6M93BA)
Step Description
26
Mount the replacement assembly in the vacated position.
Note: When replacing the screws, align carefully before tightening to avoid stripping. Tighten the
screws, alternating until all are equally tight. Do not "cinch down" any one screw until all are
properly aligned; no binding or force needed to turn.
27
Reattach any cables removed in step 7 in reverse order.
Note: Verify the cable markings (identification) or attach labels to the cables for correct positioning.
WARNING
Incorrect positioning of jumper may cause loss of AMA.
28
Verify the repair by switching disk modes back to PRIME.
Enter:
>DISK MODE xx (cr)
where: xx = disk mode = AP = A PRIME
The DPP will begin a disk copy this may take several hours, depending on how much data
is on the disk and the capacity of the disk.
Proper response:
DISK MODE: AP (from disk mode AO)
or
DISK MODE: BP (from disk mode BO)
29
Remove the insulating material, if used. Route all wires and cables to avoid pinching or
crimping when the rear panel is reinstalled.
30
Lift the hinged circuit assembly gate back to its vertical position and tighten the two screws
loosened in step 6.
