Step 3.
Ensure that all fan modules are removed from the chassis before sliding in the I/O baseboard or
both the fans and the I/O baseboard can be damaged.
Step 4.
Align the I/O baseboard assembly rails with the chassis slots and slide the assembly into the
chassis until it stops against the midplane riser board socket.
CAUTION
Ensure the I/O baseboard locking lever is in the up position to engage correctly with
the midplane riser board socket.
Step 5.
With the I/O board flush against the midplane riser board socket, push down firmly on the locking
lever until the I/O baseboard plugs all the way into the midplane riser board socket and the locking
lever clicks into place on the chassis wall (Figure 6-21).
Step 6.
Replace the three chassis fan units. (See “Replacing a Hot-Swappable Chassis Fan Unit” on
page 206.)
Step 7.
Plug all external cables into the ports at the rear of the chassis.
CAUTION
When plugging the SCSI cables, note the labeling on the SCSI A and SCSI B channel
cables. You must match each cable with its appropriate socket on the SCSI HBA. If
the cables are mismatched, your system may not reboot. Both cables and sockets are
clearly marked with the correct channel.
