OLX Dividers

OLX Dividers

OLX dividers are located on the I/O baseboard assembly between the PCI cards. Six OLX dividers provide
short circuit protection to the hot-pluggable 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 baseboard, to the top of the divider. The light pipes enables you
to view the LED status when the top cover is removed.
Ensure that the system is powered off and all power sources have been disconnected
WARNING
from the server before 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

NOTE An alternative method of removing OLX dividers is to remove all OLX dividers at once by
removing the rack they are mounted in from the I/O baseboard assembly, 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 four Torx T15 fasteners.
To remove an OLX divider, follow these steps:
Step 1. If rack-mounted, slide the server out from the rack until it stops. (See "Accessing a Rack-Mounted
Server" on page 177.)
Step 2. Remove the top cover. (See "Removing the Top Cover" on page 182.)
