I/O board replacement
Complete the following steps to remove the I/O board.
Note: When replacing the I/O board, you must either update the system with the
latest Remote Supervisor Adapter firmware code and BIOS code from
www.ibm.com/pc/support, or restore the pre-existing firmware and BIOS code
that the customer provides on a diskette or CD image.
1. Read “Installation guidelines” on page 71., the safety notices at “Safety notices
(multi-lingual translations)” on page 205., and “Handling electrostatic
discharge-sensitive devices” on page 204..
2. Turn off the server (see “Turning off the server” on page 11) and disconnect all
power cords and external cables.
3. Remove the PCI brick from the server (see “PCI brick” on page 125) and place
it on a clean work surface.
4. Remove the centerplane by turning the two centerplane thumbscrews to release
it (see “Centerplane” on page 127); then, carefully lift the centerplane out of its
socket and place it on a static-protective surface.
5. The replacement I/O board may be shipped with a cam block.
If this is the case, complete the following steps to replace the cam block:
a. Remove the two screws securing the cam block to the chassis and set them
in a safe place; then, remove the cam block from the server.

b. Position the replacement cam block in the server so that the apertures in the
cam block are aligned with the apertures in the chassis; then, use the
screws that were removed in step 5a to secure the cam block to the
chassis.

Modules will install properly in the server.
