Note:
•
Read “Before you begin” on page 136.
•
Read “Safety information” on page 257.

Read “Handling electrostatic discharge-sensitive devices” on page 260.
Complete the following actions to install the I/O baseboard:
1.
Install the I/O Baseboard into the I/O Baseboard tray and by tightening the nine
screws and two jackscrews.
2.
Orient the I/O Baseboard and tray assembly such that the connector end faces the
Sideplane.
3.
Angle the I/O Baseboard such that the side with the two extraction/installation
levers lowers into the chassis first.
4.
Slide the lever end of the I/O Baseboard against chassis frame then lower the
connector end into the chassis.
5.
Slide the I/O Baseboard towards the Sideplane until levers align with the locking
slots.
6.
Rotate the levers downward to press the I/O Baseboard securely into the
Sideplane.
7.
Install the plastic shield over the I/O Baseboard and tighten the two thumbscrews
that secure the shield and the board in the chassis.
8.
Install the 5 Volt and 3.3 Volt DC-DC converters on the Sideplane. The voltages
are marked on the power supplies (
1
) and near the sockets on the baseboard.
Note:
Do not exert excessive force if the converters don't install easily. Blocked
pins (
2
(5.0 volt converter ’s connector) and
3
(3.3 volt converter ’s
connector)) and corresponding blank pins on the Sideplane board's
sockets prevent incorrect insertion. Attempting to forcibly insert the
wrong DC-DC converter in a Sideplane socket can bend the socket's pins.
9.
Install the protective cover over the converters in the Sideplane, and secure the
cover with the thumbscrew.
10. Connect the cable to the external SCSI port at both ends: one to the I/O Baseboard
and the other to the rear of the chassis with the captive thumbscrew.
11. Connect the SCSI interconnect cable to the front of the I/O Baseboard.
