Removing the Mass Storage Module
1 Determine what SCSI bus addresses are in use by following the procedure
in the previous section. Be sure to write down this information.
2 Shut down your system by typing shutdown -h 0 Enter and responding
to the confirmation message.
3 Turn off the power to the Model 748i VMEbus chassis.
4 Unplug the power cables to the Model 748i.
5 Unplug the external SCSI cable from the board computer.
6 Inside each handle for the mass storage module is a slotted captive screw.
Unscrew each of the two screws about 7 turns (until it pops out).
7 Pull the mass storage module all the way out and place it on a clean, se-
cure, and static-free surface.
Removing a Device from the Mass Storage Module
CAUTION: Hard disk drives are vulnerable to physical shock. Dropping a hard disk drive
from even a small height will damage its heads and platters. Always handle
hard disk drives with extreme caution. Do not place a hard disk drive upside
down on any surface.
Follow these steps to remove a drive.
1 Unplug power and SCSI cables for the drive.
2 Loosen the screws for that drive underneath the mass storage module.
3 Slide the drive back in its mounting keyhole slots about 12 mm (0.5-in.)
to free the screws. Then lift the drive up and out of the module.
4 Repeat this procedure, as needed, if you are removing additional devices.
