User Service Guide, Third Edition - HP Integrity rx4640 Server

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 off 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 can result in personal injury or damage to equipment.
CAUTION: Observe all ESD safety precautions before attempting this procedure. Failure to
follow ESD safety precautions can 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.
1. If rack mounted, slide the HP server out from the rack until it stops. See “Extending the
Server From the Rack” (page 31).
2. Remove the front bezel. See “Removing the Front Bezel” (page 34).
3. Remove the top cover. See “Removing the Top Cover” (page 36).
4. To unlock the rear edge of the PCI divider, slide open the latch on the rear PCI cage wall.
Figure 4-28 shows how to open the OLX divider latch.
