Removing the Mainboard

Removing the Mainboard

Procedure

  1. Record the iBMC, BIOS, and CPLD firmware versions of the mainboard.

    You can obtain the firmware version information on Information > System Info > Product Info > Mainboard Info of the iBMC WebUI or by running the ipmcget -d version command on the iBMC CLI.

  2. Confirm the iBMC and BIOS configuration for quick recovery after replacing the mainboard.
  3. Export the iBMC/BIOS configuration files. After the replacement, you can import the configuration files to quickly restore the server configuration.

    For details, see iBMC WebUI > Configuration > Import/Export in FusionServer Pro X6800 Server iBMC (V300 to V369) User Guide.

    NOTE:
    • 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 details, see iBMC WebUI > Configuration > Import/Export in FusionServer Pro X6800 Server iBMC (V300 to V369) User Guide.
    • The iBMC and BIOS configuration files exported from the iBMC contain the configuration list. For details, see "Configuration File Description" in FusionServer Pro X6800 Server iBMC (V300 to V369) User Guide.
    • If the iBMC of the mainboard to be replaced cannot be accessed or the iBMC and BIOS configuration files are not exported before the mainboard is replaced, you need to manually configure the iBMC and BIOS after replacing the mainboard.

  4. Power off the server node.

    For details, see Power-Off Procedure.

  5. Remove the server node.

    For details, see Removing an XH628 V5.

  6. Place the server node on the ESD workstation.
  7. Remove the drive drawer.

    For details, see Removing the Drive Drawer.

  8. Determine the position of the mainboard.
  9. Remove the cable carrier.

    For details, see Removing the Cable Carrier.

  10. Remove all cables from the mainboard.

    For details, see Internal Cabling.

  11. Remove the TPM.

    For details, see Removing the TPM.

  12. Remove the screw-in RAID controller card.

    For details, see Removing the Screw-in RAID Controller Card.

  13. Remove the supercapacitor if there is any.
