Step 1. Disconnect all cables on the system board that go to connectors in the compute tray. See "Internal
cable routing" on page 35.
Step 2. Press the release clips and slide the system board out of the compute tray.
After you remove the system board:
• If you removed the upper system board and are not installing another system board , install a system
board filler, install the compute tray, and install the front cover. See "Install a system board filler" on page
313, "Install a compute tray" on page 307, and "Install the front cover" on page 322.
• If you removed the lower system board, it must be replaced before you reinstall the upper system board or
filler.
• If you are instructed to return the system board, follow all packaging instructions, and use any packaging
materials for shipping that are supplied to you.
Important: Before you return the system board, make sure that you install the CPU socket dust covers
from the new system board. To replace a CPU socket dust cover:
1. Take a dust cover from the CPU socket assembly on the new compute system board and orient it
correctly above the CPU socket assembly on the removed system board.
2. Gently press down the dust cover legs to the CPU socket assembly, pressing on the edges to avoid
damage to the socket pins. You might hear a click on the dust cover is securely attached.
3. Make sure that the dust cover is securely attached to the CPU socket assembly.
• If you are planning to recycle the system board, follow the instructions in "Disassemble the system board
for recycle" in Maintenance Manual for compliance with local regulations.
Install a system board
Install a system board by inserting it in the compute tray, pushing it in until it locks in place, and connecting
the cables.
