Procedure

Depending on the needs, do one of the following:
- If you are going to replace the system I/O board and reuse the processor board, install a new system I/O board onto the processor board.
- If you are going to replace the processor board and reuse the system I/O board, install the existing system I/O board onto a new processor board.
1. Install the system I/O board onto the processor board.
  1. Align the system I/O board with the connector on the processor board, and use both hands to push the system I/O board and slightly insert it into the connector.
    Note
    To prevent the contact of the system I/O board from damage, ensure that the system I/O board is aligned correctly with the connector on the processor board, and remains as horizontal as possible during the insertion.
