PCIe/XAUI Riser Overview
PCIe/XAUI cards are installed on vertical risers. You must remove the PCI cross
beam and relevant riser to access a PCIe/XAUI card.
Caution – This procedure requires that you handle components that are sensitive to
static discharge. This sensitivity can cause the component to fail.
Caution – Ensure that all power is removed from the server before removing or
installing expansion cards. You must disconnect the power cords before performing
this procedure.
You must remove PCIe riser 2 when servicing the SCC module.
You must remove all three PCIe/XAUI risers when servicing the motherboard.
▼ Remove a PCIe/XAUI Riser
1. Power off the server.
See “Removing Power From the System” on page 60.
2. Disconnect all power cables.
See “Disconnect Power Cords From the Server” on page 62.
3. Attach an antistatic wrist strap.
4. Disconnect any data cables connected to the cards on the PCIe/XAUI riser being
removed.
Label the cables to ensure proper connection later.
5. Slide the server out of the rack.
See “Extend the Server to the Maintenance Position” on page 63
6. If you are servicing a PCIe/XAUI card, locate its position in the system.
7. Remove the PCI cross beam.
a. Loosen the two captive Phillips screws on each end of the removable PCI
cross beam.
b. Slide the PCI cross beam back to remove it from the chassis.
Two mushroom standoffs secure the removable cross beam to the back of the
