Remove the firmware and RoT security module

Procedure

1. Make preparations for this task.
   1. Perform OneCLI commands to back up the UEFI settings. See OneCLI commands that save configuration settings.
   2. Perform both OneCLI commands and XCC actions to back up the XCC settings. See OneCLI commands that save configuration settings and Using XCC to back up the BMC configuration.
   3. Power off the node (see Power off the node); then, disconnect all external cables from the node.
   4. Remove the node from the chassis (see Remove a node from the chassis); then, carefully lay the node on a flat, static-protective surface, orienting the node with the front toward you.
      Note

      • When removing the node, note the node tray number and make sure to install the node in the same tray from which it was removed. Reinstalling the node into a different tray requires the node to be reconfigured.
      • For safety, make sure to hold the node with both hands when lifting the node.
   5. Remove the top cover (see Remove the top cover).
   6. Remove the processor heat sink (see Remove the processor and heat sink).
