- Keep NVRAM away from any objects that can cause static electricity. Static electricity can damage NVRAM data.
Special Procedure for Machines that have a Self Encrypting Drive (SED) Installed
- The machine holds data, linking the controller board and SED, created automatically during SED installation. The data, however, will not be deleted automatically at controller board replacement. Therefore, before replacing a controller board, you must delete the link data manually so that the machine can create new link data.
- Do the following steps when doing the replacement.
- Execute [Erase All Memory] on the operation panel
[System Settings] – [Administrator Tools] – [Erase All Memory] - Turn OFF the main power switch
- Replace the controller board
- Turn ON the main power switch
- Do not turn the main power ON after step 2, until after you replaced the board.
- Execute [Erase All Memory] on the operation panel
- Remove the left rear cover. (Left Rear Cover)
- Remove the HDD bracket. (HDD)
- Remove the controller bracket [A].
- Slide the controller board [A] to the right side to remove it.
- Release the guide rail [A].
Remove the NVRAMs 1 [A] and 2 [B] on the controller board.
- When installing a new controller board, install the NVRAM removed from the old board, or a new NVRAM if the old NVRAM is defective. Install the NVRAM [C] so that the indentation [B] on the NVRAM corresponds with the mark [A] on the controller board. Incorrect installation of the NVRAM will damage both the controller board and the NVRAM.
