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