Step 9. Turn the PCI-X card lock on the chassis to the closed position. This locks the PCI-X card into its slot
and the manual retention latch into the closed position.
Step 10. Press the attention button—the power LED starts to blink.
Step 11. Wait for the power LED to stop blinking—the PCI-X card is now active.
Step 12. Replace the top cover. “Replacing the Top Cover” on page 44.
Step 13. Push the HP server all the way back into the rack until it stops. See “Inserting the Server into the
Rack” on page 39.
Removing and Replacing OLX Dividers
OLX dividers are located on the I/O baseboard, between the PCI cards. Six OLX dividers provide short circuit
protection to the hot-plug PCI accessory boards by preventing inadvertent contact between boards during the
replacement or addition of a board.
Additionally, each OLX divider has two light pipes that transfer illumination from one green power LED and
one amber attention LED, mounted on the I/O board, to the top of the divider. The light pipes allow the LED
status to be easily viewed when the top cover is removed.
WARNING Ensure that the server is powered down and all power sources have been
disconnected from the server prior to removing or replacing a PCI card divider.
Voltages are present at various locations within the server whenever an ac power
source is connected. This voltage is present even when the main power switch is in
the off position.
Failure to observe this warning could result in personal injury or damage to
equipment.
CAUTION Observe all ESD safety precautions before attempting this procedure. Failure to follow ESD
safety precautions could result in damage to the server.
Removing an OLX Divider
To remove an OLX divider, follow these steps:
NOTE An alternative method of removing OLX dividers individually is to remove all OLX dividers at
once by removing the rack they are mounted in from the I/O baseboard, then removing or
replacing the individual OLX divider, and then replacing the rack back on the I/O baseboard.
The OLX divider rack is attached to the I/O baseboard with 4 torx T15 fasteners.
Step 1. If rack mounted, slide the HP server out from the rack until it stops. See “Extending the Server
from the Rack” on page 39.
Step 2. Remove the front bezel. See “Removing the Front Bezel” on page 41.
