Installing an Expansion Board
CAUTION: To avoid the risk of damage to the system or expansion boards, remove
all AC power cords before installing or removing expansion boards. Pressing the
Power On/Standby button to power down the server still provides auxiliary power to
the expansion slot and may damage the board or other system components.
To install an expansion board:
1. Open the PCI-X slot release lever and remove the expansion slot cover. Refer to
"Removing an Expansion Slot Cover" in this chapter.
2. Press the PCI-X guide clip out toward the center wall to release. The clip locks
into an open position until the board is secured.
NOTE: The PCI-X guide helps align and secure a full-sized expansion board.
