If the part number (P/N) of the drive backplane configured on the server is 03029JRY, ensure that the mainboard iBMC version is V520 or later. Otherwise, upgrade the iBMC.
If the part number (P/N) of the new mainboard is 03026NEA or 03029JRP, the mainboard iBMC cannot be rolled back to a version before V520, the BIOS cannot be rolled back to a version before V793, and the mainboard CPLD cannot be rolled back to a version before V213.

Procedure

Place the server on the ESD workstation.
Take the spare part out of its ESD bag.
Determine the position of the mainboard.
Install the mainboard.
1. Hold the handles (shown in the red circles) and tile the mainboard 10° to 15° in the arrow direction.
  Figure 6-191 Installing the mainboard (1)
2. Align the rear ports of the mainboard with the reserved holes on the rear panel of the chassis and push the mainboard in the arrow direction as far as it will go. See (1) in Figure 6-192.
3. Tighten the screws to secure the mainboard. See (2) in Figure 6-192.

Install the baffle plate for ports.
1. Tilt the baffle plate, insert the baffle plate into the fixing holes and press it firmly. See (1) in Figure 6-193.
  
  When pressing the baffle plate, hitch the baffle plate on the connector gently to avoid damage to the connector.
2. Tighten the screws to secure the baffle plate. See (2) in Figure 6-193.

Power on the server.
For details, see Power-On Procedure.
Check the indicator status. If the health status indicator is steady green, the server is running properly.
For details, see Front Panel Indicators and Buttons.
Burn the original SN into the new mainboard. For details, see section "Modifying Electronic Labels" in the SmartKit User Guide (for Engineers).
- Only authorized engineers can download the ElabelTool plug-in package, import it to SmartKit, and modify electronic labels.
- If the original device SN is not burnt in the new mainboard, the iBMC and OS cannot obtain the device SN. This may affect the running of some services or the monitoring and management on the device.
After the mainboard is replaced, the LOM is replaced and the MAC address of the LOM is changed. If the LOM is used for transferring data, you need to configure the LOM data.
After the mainboard is replaced, the iBMC and BIOS settings are restored to the default settings of the new mainboard. Configure the iBMC and BIOS based on service requirements.
- The iBMC supports import and export of configuration files from version 2.32.
- After replacing the mainboard, import the iBMC and BIOS configuration files that are exported from the iBMC. However, the exported configuration files do not contain password information. You need to manually configure the password for the iBMC user. For iBMC V549 and earlier versions, see "Import/Export" in the Atlas 800 Inference Server iBMC User Guide (Model 3010). For iBMC V600 and later versions, see "Configuration Update" in the Atlas 800 Inference Server iBMC User Guide (Model 3010).
- The iBMC and BIOS configuration files exported from the iBMC contain the configuration list. For details, see "Configuration File Description" in Atlas 800 Inference Server iBMC User Guide (Model 3010).
- If the iBMC and BIOS configuration files are not exported before the mainboard is replaced, manually configure the iBMC and BIOS data after replacing the mainboard.
Upgrade the mainboard firmware (iBMC, BIOS, and CPLD) and Smart Provisioning to the latest version.
For details, see the Atlas 800 Inference Server Upgrade Guide (Model 3010).
