Replacing a power distribution board
Your server uses a power distribution board to enable the hot-swap capability and distribute
power to the system. If the power distribution board fails, you will need to turn off the
server and disconnect all AC power to the system prior to replacing it.
To replace a power distribution board:
1 Follow the instructions in “Preventing static electricity discharge” on page 65.
2 Follow the instructions in “Opening the server case” on page 66.
3 Remove the power supply module (remove both if two are installed) by following the
instructions in “Replacing a power supply module” on page 134.
4 Remove the processor air baffle by following the instructions in “Removing and
installing the processor air baffle” on page 67.
5 Remove the system board by following the instructions in “Replacing the system
board” on page 149.
6 Remove the SCSI backplane by following the instructions in “Replacing the SCSI
hot-swap backplane” on page 139.
7 Disconnect all power cables from the power distribution board, noting their locations
and orientation. (You will reconnect the cables after you install the new board.)
