PCI riser card replacement
To replace the PCI riser card, do the following:
1. Before handling any card, board, or DIMM, be sure to use your electrostatic discharge strap to
minimize static-electric discharge. Refer to "Handling static-sensitive devices" on page 310.
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 that 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. It is strongly recommended that the system drawer be
removed from the rack.

b. To ensure the PCI-riser-card docking connectors are fully seated, using your thumbs, alternately
push down on the two "push" labels that are mounted on the PCI riser card. Push until no more
movement is felt and then push down hard again on both "push" 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.
5. Replace the seven hex-head screws and the two 5.5-mm nuts that secure the PCI riser card to the
CEC backplane and chassis.
Note: For proper alignment, insert all screws before tightening.
6. Replace the plastic protector on top of the riser card.
7. Reconnect the power, signal, and SCSI cables.
8. Replace the PCI-X hot plug separators
9. Replace all adapters to their proper locations as described in "PCI-X adapter replacement" on
page 325.
10. Reconnect all of the labeled PCI-X adapter cables to their respective PCI-X adapters.
11. Replace the processor card assembly #2 as described in "Processor book insertion" on page 344. If
you removed a processor filler panel, replace the processor filler panel now.
