• The ID for each equipment is registered on the PU board, the CU board and SU board. So, if
their replacement is required, be sure to replace only one board at a time. Do not replace the
CU board and the SRAM board (for the CU board) together.
• If both the PU board and CU 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.
• When the HDD requires replacement, see “6.2.3Precautions and procedures when replacing
the HDD”.
• When the CU board requires replacement, see “6.2.4Precautions and Procedures when
replacing the CU board”.
• When SRAM board requires replacement, see “6.2.5Precautions and procedure when
replacing the SRAM board (for the CU board)”.
