NOTE: Since the bulkhead and system board openings are larger than the
standard 15-pin LAN connector, the connector assembly includes a
small filler plate to cover the bulkhead opening from the inside.

and computer unit bulkhead, and insert the two screws as shown in Figure 9Ć16.

Figure 9-16 Securing the I/O Expansion Board to the Computer Unit Bulkhead
To install a replacement I/O expansion board, or to reinstall one removed for access to
the system board, skip Step 5 through Step 7 and continue with Step 8. To install a
new I/O board in a system that previously had none, continue with Step 5.
5. Secure the SCSI cable's 50-pin CHAMP connector to the computer unit
bulkhead as shown in Figure 9Ć17.
NOTE: To create more room within the chassis for connecting the SCSI B
connector to the bulkhead, you may need to move any full-height disk
in the rear device bay. Simply remove the 8 screws that secure the rear
drive assembly to the chassis, then slide the assembly forward. (Refer
to the illustrations in Chapter 7, if necessary. )
