Replacing the I/O board and power backplane assembly
This section contains information about replacing the I/O board and power
backplane assembly.
Note:
Complete the following steps to remove the I/O board and power backplane
assembly:
Description
The default position is pins 1 and 2 (use the primary boot block
during startup). Move the jumper to pins 2 and 3 to use the
secondary boot block during startup. For more information about
recovering the BIOS code, see "Recovering BIOS code" on page 24.
The default position is pins 1 and 2. Changing the position of this
jumper to pins 2 and 3 bypasses the power-on password check.
Changing the position of this jumper does not affect the
administrator password check if an administrator password is set. If
the administrator password is lost, the operator information panel
must be replaced.
For more information about passwords, see "Password override
jumper" on page 25 and the section on using passwords in the
User's Guide on the IBM xSeries Documentation CD.
The default position is pins 1 and 2. Move the jumper to pins 2 and
3 to prevent a Wake on LAN (WOL) packet from waking the system
when the system is in the powered-off state.
The default position is pins 1 and 2. Move the jumper to pins 2 and
3 when an IXA adapter is installed in PCI slot 3.

1. Turn off the server and all peripheral devices; then, disconnect all power cords
and external cables.
Note: The Remote Supervisor Adapter II has external cable connections that
must also be disconnected.
2. Remove the top cover (see "Removing the cover and bezel" on page 32).
3. Remove all fans.
4. Remove the memory cassette.
5. Lift the microprocessor-tray release latch.
6. Remove the microprocessor tray assembly (see "Microprocessor tray
assembly" on page 68).
Attention:
The microprocessor tray is heavy. Pull the tray part-way out of the
server, reposition your hands to grasp the body of the tray, and then pull the
tray out the rest of the way.
7. Remove the power supplies (see steps 4a on page 52 through 4c on page 52
at "Installing a hot-swap power supply" on page 51).
8. Disconnect all cables from the I/O board.
