PCI Riser Card Replacement
To replace the PCI riser card, do the following:
1. Before handling any card, board, or memory DIMM, be sure to use your electrostatic discharge strap
to minimize static-electric discharge. Refer to “Handling Static-Sensitive Devices” on page 423.
2. If necessary, remove the PCI riser card from the antistatic package.
3. Carefully grasp the PCI riser card along two edges, and align the four connectors located on the
bottom side of the PCI riser card with the four standoff connectors located on the CEC backplane.
4. Ensure you have proper alignment of the PCI riser card connectors. Seat the PCI riser card into the
CEC backplane connectors.
a. To perform this procedure requires a considerable amount of force when removing or installing the
PCI riser card from its docking connectors. If you are servicing a Model 6C4, it is strongly
recommended that the system drawer be removed from the rack. If you are servicing a Model
6E4, it is strongly recommended that the system be placed on its side, on a flat and stable
surface. To avoid potential breakage, the Model 6E4 stabilizer foot closest to the desktop or floor
is free from resting on any surface.

push down on the two

labels. This alternate pushing
technique is allowed only for this card.
Note: Mounted below the CEC backplane is an aluminum plate. The plate aids in stiffening the
CEC backplane and keeps it from flexing or cracking when the PCI riser card is inserted.
c. If you experience any problem when you boot the system, repeat substep 4, but the second time,
you must push harder.
