CAUTION: Before you perform this procedure you must turn off the system and
disconnect it from its power source. See your System Information Guide for
complete information about safety precautions, working inside the computer,
and protecting against electrostatic discharge.
NOTE: The following two procedures assume that you have already removed the
system covers and performed the initial steps of "Installing a ROMB Card" or
"Removing a ROMB Card" in your Installation and Troubleshooting Guide.
Removing the SCSI Backplane Board
1 Pull each hard-drive carrier partially out of its slot, approximately 2.5 cm (1 inch).
2 Disconnect the diskette-drive interface cable from the FLOPPY connector on the
backplane board. See Figure 1-1.
3 Disconnect the CD drive interface cable from the CD_ROM connector on the
backplane board. See Figure 1-1.
4 Press the release latch in toward the backplane board and use the handle to pull the
board out of its connector and up out of the chassis. See Figure 1-1.
Installing the SCSI Backplane Board
1 Insert the SCSI backplane board into the chassis:
a Fit the metal tabs (one tab at each end of the backplane) into the slots in the
chassis wall and lower the backplane into the chassis, ensuring that the CD and
diskette drive interface cables are not caught under the backplane. See Figure 1-1.
b Press down firmly over the handle to seat the backplane in its connector.
2 Pivot the release latch out into the securing slot in the chassis.
3 Connect the CD drive interface cable to the CD_ROM connector on the backplane
