• If you are replacing the system board as part of a maintenance operation, remove all of the following
components from the system board; then, place them on a static-protective surface or install them on the
new system board:
– Processor (see “Processor and heat sink replacement” on page 190)
– Memory modules and memory module fillers (see “Memory module replacement” on page 173)
– Memory air baffles (see “Memory air baffle replacement” on page 170)
– Cables (see “Internal cable routing” on page 40.)
• 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
114, “Install a compute tray” on page 117, and “Install the front cover” on page 132.
• 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.

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.

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” on page 267 for compliance with local regulations.
