Installing or Replacing Server Components
Replacing an I/O Riser
The I/O riser is a modular PCIe form-factor card that has a designated motherboard socket inside the
server (see
Figure 3-23
). The module provides the external VGA video and RS-232 serial connectors for
the rear panel of the server. See
Figure 3-22
.
The I/O riser also provides two internal slots for Cisco FlexFlash cards. For more information about
Cisco FlexFlash cards, see
Replacing a Cisco Flexible Flash Card, page 3-39
.

I/O Riser, Including Cisco FlexFlash Slots
To install or replace an I/O riser, follow these steps:
Step 1
Remove the I/O riser that you are replacing (see
Figure 3-23
):
a.
Power off the server as described in the
“Shutting Down and Powering Off the Server” section on
page 3-7
.
b.
Slide the server out the front of the rack far enough so that you can remove the top cover. You might
have to detach cables from the rear panel to provide clearance.
Caution
If you cannot safely view and access the component, remove the server from the rack.
c.
Remove the top cover as described in
“Removing and Replacing the Server Top Cover” section on
page 3-8
.
d.
Disconnect any external cables from the I/O riser ports.
e.
Use a Number 1 Phillips-head screwdriver to remove the single screw that secures the I/O riser rear
panel tab to the chassis.
f.
Lift the I/O riser straight up from the motherboard connector.
Note
Lift up on both ends of the I/O riser evenly to avoid damaging its connector.
