Removing the I/O board
When replacing the I/O board, you must either update the server with the latest
SAS firmware or restore the pre-existing firmware from a diskette or CD image.
The I/O board contains three-pin jumper blocks. See “I/O board internal connectors
and jumpers” on page 8 for the location and description of each jumper block.
To remove the I/O board, complete the following steps.
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 115.
2. Turn off the server and peripheral devices, and disconnect the power cords and
all external cables necessary to replace the device.
3. Unlock the front cover (tower model only) and remove the top cover (see
“Removing the top cover, bezel, and front cover” on page 119).
4. Note where each cable is connected, and disconnect all internal and external
cables from the I/O board.
5. Remove the cable retaining clip that secures the SAS cables and other cables
and move the cables out of the way.
6. Open the retention latches on both ends of the I/O board and pull the board
from the server slightly.
