5.3 Replacement of PC Boards and HDD
<CAUTION IN REPLACING PC BOARDS>
The ID for each equipment is registered on the LGC board, the DRV board, the SYS board and the SLG
board. So, if their replacement is required, be sure to replace only one board at a time.
If more than one of the LGC board, the DRV board and the SYS board require replacement, replace
them in the following procedure.
1) First, replace one of the board to be replaced.
2) Turn the power ON and confirm that "READY" is displayed.
3) Turn the power OFF.
4) Replace another board that requires replacement.
5) Repeat steps 2 to 4.
The LGC board and DRV board can be replaced without other settings.
When the HDD requires replacement, see “5.3.1 Replacing HDD”.
When the SYS board requires replacement, see “5.3.2 Replacing SYS board”.
When the SLG board requires replacement, see “5.3.3 Replacing SLG board”.
When NVRAM requires replacement or clearing, see “5.3.4 NVRAM replacing and clearing”.
5.3.1 Replacing HDD
<CAUTION IN REPLACING HDD>
When the HDD is replaced, it is necessary to back up the data in the HDD before replacing and to
recover them after replacing.
Notes:
1. To maintain the security, ask users to perform the backup/restore for users’ data/information
in the HDD. The service technician can perform them only when users permit it.
2. Some data in the HDD cannot be backed up and can be kept only on the paper.
3. When 08-690 is performed, the HDD self-certificate is not available, so the SSL-related set-
ting becomes disabled.
The procedure for replacing the HDD is as follows.
