Install the system I/O board or processor board
Follow instructions in this section to install the system I/O board or processor board.
About this task
This task must be operated by trained technicians that are certified by Lenovo Service. Do no attempt to remove or install it without proper training and qualification.
When the server has an L2AM module (Closed loop cooling module) installed, you must apply for a handle (L2AM heat sink bracket) first if you need to install or remove the processor board, I/O board, processor and PIB board. However, while replacing the old L2AM module with a new one, you do not need to apply for a handle (L2AM heat sink bracket) as the new L2AM module contains it.
Power off the server and peripheral devices and disconnect the power cords and all external cables. See Power off the server.
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.
Go to Drivers and Software download website for ThinkSystem SR635 V3 to see the latest firmware and driver updates for your server.
Go to Update the firmware for more information on firmware updating tools.
- 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.
- Install the fan board and the PIB board onto the processor board. See Install the fan board and Install the PIB board.
- Depending on your need, do one of the following:
Figure 1. Installing the system I/O board onto the processor board
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.
- 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.NoteTo prevent the contact of the system I/O board from damage, ensure that the system I/O board is aligned correctly with the connector on the processor board, and remains as horizontal as possible during the insertion.
- Install the screws to fix the system I/O board into place.
- (Optional) If you are replacing the system I/O board, install the firmware and RoT security module that is removed from the old system I/O board onto the new system I/O board. See Install the firmware and RoT security module.
- Install the MicroSD card (Install the MicroSD card).
- Install the system board assembly into the server. Figure 2. System board assembly installation
- Hold the lift handle 1 and the release pin 2 at the same time to lower the system board into the chassis.
- Slide the system board to the rear of the server until the system board snaps into position. Ensure that:
The rear connectors on the new system board are inserted into the corresponding holes in the rear panel.
The release pin 2 secures the system board in place.
After you finish
Reconnect all the required cables to the same connectors on the system board assembly. See Internal cable routing.
Ensure that all components have been reassembled correctly and that no tools or loose screws are left inside the server.
Reinstall the top cover. See Install the top cover.
If the sever was installed in a rack, reinstall the server into the rack. See Install the server to rack.
Reconnect the power cords and any cables that you removed.
Power on the server and any peripheral devices. See Power on the server.
If the processor board is replaced, update the vital product data (VPD). See Update the Vital Product Data (VPD).
Machine type number and serial number can be found on the ID label, see Identify the server and access the Lenovo XClarity Controller.
Download and install the latest device drivers: Drivers and Software download website for ThinkSystem SR635 V3.
Update the system and device firmware. See Update the firmware.Note(Lenovo Trained technicians only) If you have replaced the
firmware and RoT security module, update the firmware to the specific version supported by the server. See Tip for replacing a Firmware and RoT Security Module.
If hiding TPM firmware is needed, see Hide/observe TPM.
Optionally, enable UEFI Secure Boot. See Enable UEFI Secure Boot.
