- Reinstall the System Remind button assembly (air divider) by sliding it into the
Caution - After replacing the motherboard, inspect the dividing wall gasket, and then install the
plastic dividing wall securely. This dividing wall maintains a pressurized seal between the server
cooling zones. Without this pressurized seal, the power supply fans will not be
able to draw enough air to cool the drives properly.
- Reinstall all memory risers and filler panels.
See Install a Memory Riser.
See Install a Memory Riser Filler Panel.
- Reinstall the cable cover.
- Reconnect all cables from the power supply backplane, drive backplane, and fan board
to their original locations on the motherboard.

- Prior to powering on the server, connect a terminal or a terminal emulator
(PC or workstation) to the service processor SER MGT port.
Refer to the SPARC T4-2 Server Installation Guide for instructions.
If the service processor detects the host firmware on the replacement motherboard is
not compatible with the existing service processor firmware, further action will be suspended
and the following message will be displayed:
Unrecognized Chassis: This module is installed in an unknown or

version that supports this chassis.
If you see the preceding message, continue to Step 17. Otherwise, skip to Step 19.
- Download the system firmware.
- If necessary, configure the service processor NET MGT port so that it can
access the network.
Refer to the Oracle ILOM documentation for network configuration instructions.
- Log in to the service processor through the NET MGT port.
- Download the system firmware.
Follow the firmware download instructions in the Oracle ILOM documentation.
Note - You can load any supported system firmware version, including the firmware version that
had been installed prior to replacing the motherboard.
- If necessary, reactivate any RAID volumes that existed prior to replacing the motherboard.
If your system contained RAID volumes prior to replacing the motherboard, see Reactivate RAID Volumes
- Power on the server.
See Power On the Server (Oracle ILOM) or Power On the Server (Power Button).
- (Optional) Transfer the serial number and product number to the FRUID of the
Do this if you need the replacement to have the same serial number
