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 3-22). The module provides the external VGA video and RS-232 serial connectors for the rear panel of the server. See Figure 3-21.

The I/O riser also provides two internal slots for SD cards.

To install or replace an I/O riser, follow these steps:

Step 1 Remove the I/O riser that you are replacing (see Figure 3-22):

a.Power off the server as described in Shutting Down and Powering Off the Server, page 3-8.

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, page 3-9.

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.
