Removing the I/O Backplane Assembly From the Server
Observe the following warning and cautions before removing the I/O backplane assembly.
CAUTION: Observe all ESD safety precautions before attempting this procedure. Failure to
follow ESD safety precautions may result in damage to the server.
Record the slot location of all PCI cards as they are removed. The only compatible slot across the
two I/O backplanes is the PCI-X 133 MHz slot. If you have more than one PCI-X card in your
rx2660 server, it needs to be upgraded to a PCIe card. If you use a 266 MHz card in a 133 MHz
slot, the card runs at the lower speed.
To remove the I/O backplane assembly, follow these steps:
1. Disconnect any cables attached to the I/O cards in the I/O backplane assembly.
2. Loosen the two captive screws that hold the I/O backplane assembly to the system board.
See Figure B-1 for the screw locations.
a. Press the blue button to release the black knob.
b. Turn the black knob counterclockwise until the captive screw is free from the system
board.

3. Lift the assembly straight up and out of the server. Figure B-2 (page 207) shows the PCI-X
I/O backplane assembly.
4. Remove the PCI-X cards from the I/O backplane assembly by doing the following:
a. Remove the bulkhead T-15 thumbscrews from the I/O backplane assembly.
b. Pull the cards up and out of the I/O backplane assembly.
