Step 5. Remove the 2 jack screws in the front bulkhead that secure the system board to the water-cooled
technology tray, and put the screws in a safe place.
Step 6. Carefully hold on to the edges of the system board. Avoid touching the connectors on the system
board. Lift and tilt the system board upwards and slightly push the system board away from the
front bulkhead. Then carefully lift and remove the system board from the server.

Note:
When you remove the system board from the server, avoid touching the cable clips on the
side of the chassis and the connectors on the system board. Be careful not to damage any
surrounding components inside the chassis.
If you are instructed to return the server component or optional device, follow all packaging instructions, and
use any packaging materials for shipping that are supplied to you.
Attention:
Make sure to place the socket cover for the microprocessor socket on the system board before
returning the system board.
Replacing the system board
Use this information to replace the system board.
Read the safety information in Safety and Installation guidelines.
If you are replacing a server component in the water-cooled technology tray, you need to remove the water-
cooled technology tray from the chassis enclosure and refer to the “Removing a water-cooled technology
tray from a chassis” on page 139 and “Installing a water-cooled technology tray in a chassis” on page 140
sections.
Notes:
1. When you reassemble the components in the server, be sure to route all cables carefully so that they are
not exposed to excessive pressure.
2. When you replace the system board, you must either update the server with the latest firmware or
restore the pre-existing firmware from a diskette or CD image. Make sure that you have the latest
firmware or a copy of the pre-existing firmware before you proceed. See “Updating the firmware” on
page 31, “Updating the Universal Unique Identifier (UUID)” on page 47, and “Updating the DMI/SMBIOS
data” on page 49.
