• Power off the server and peripheral devices and disconnect the power cords and all external cables. See
“Power off the server” on page 73.
• Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-
sensitive components in their static-protective packages until installation, and handling these devices with
an electrostatic-discharge wrist strap or other grounding system.
• After replacing the system I/O board or processor board, always update the server with the latest firmware
or restore the pre-existing firmware.
Firmware and driver download: You might need to update the firmware or driver after replacing a
component.
• Go to
https://datacentersupport.lenovo.com/products/servers/thinksystem/sr650v3/7d75/downloads/driver-
list/
to see the latest firmware and driver updates for your server.
• Go to
“Update the firmware” on page 445 for more information on firmware updating tools.

Procedure
Step 1. Touch the static-protective package that contains the new part to any unpainted surface on the
outside of the server. Then, take the new part out of the package and place it on a static-protective
surface.
Step 2. (Optional) If you are replacing the system I/O board, do the following:
1. Install the firmware and RoT security module removed from the old system I/O board onto the
new system I/O board. See
“Install the firmware and RoT security module” on page 243.
2. Install the MicroSD card removed from the old system I/O board onto the new system I/O
board. See
“Install the MicroSD card” on page 141.
Step 3. Depending on your need, do one of the following:
• If you are going to replace the system I/O board and reuse the processor board, install a new
system I/O board onto the processor board.
• If you are going to replace the processor board and reuse the system I/O board, install the
existing system I/O board onto a new processor board.

a. Align the system I/O board with the connector on the processor board, and use both hands
to push the system I/O board and slightly insert it into the connector.
