Pci Riser Card - IBM pSeries 630 6C4 Service Manual

PCI Riser Card

Attention: To perform this procedure requires a considerable amount of force when removing or
installing the 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, make sure that the Model 6E4 stabilizer foot closest to the desktop or floor does not
rest on any surface.
Before performing the following procedure, read "Safety Notices" on page xi.
PCI Riser Card Removal
To remove the PCI riser card, do the following:
1. If you are servicing a Model 6E4, open the bezel door.
If you are servicing a Model 6C4 rack-mounted drawer, open the front and rear rack doors.
2. Shut down the system as described in either "Stopping the System without an HMC Attached" on
page 424, "Stopping the System with an HMC Attached and AIX Installed" on page 424, "Stopping the
System with an HMC Attached and AIX Installed" on page 424, or "Stopping the System with an HMC
Attached and Linux Installed" on page 425.
3. Disconnect the power source from the system.
Note: This system may be equipped with a second power supply. Before continuing with this
procedure, ensure that the power source to the system has been completely disconnected.
4. Label and disconnect all adapter cables, located at the rear of the system unit.
5. If you are servicing a Model 6C4, place the system drawer into the service position as described in
"Placing the Model 6C4 into the Service Position" on page 429.
6. Remove the service access cover as described in "Service Access Cover Removal (Model 6C4)" on
page 431 or "Service Access Cover Removal (Model 6E4)" on page 436.
7. Disconnect all power and signal cables from the media drives, located in media bay 1 and media bay
2. Then remove the media drives as described in "Media Removal" on page 466.
8. Remove the front bezel as described in "Front Bezel Removal (Model 6C4)" on page 442 or "Front
Bezel Removal (Model 6E4)" on page 443.
9. Remove the media device support shelf by loosening the thumbscrew and grasping the back edge of
the shelf, sliding it back, then lifting it up and out of the system chassis.
Note: The support leg located on the bottom of the support shelf is used to deactivate a microswitch.
The microswitch is located on the CEC backplane and when deactivated, removes power to
many of the components and connectors located on the CEC backplane. This support shelf
must be correctly seated and secured in position after any new FRU is added to the system and
you perform a system boot.
10. Record the slot number and location of each adapter.
11. Remove the processor assembly #2 as described in "Processor Card Removal" on page 488. If your
system is equipped with a processor filler panel instead of a second processor card assembly,
remove the processor filler panel.
12. 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.
13. Remove the PCI adapters as described in "Non-Hot-Pluggable PCI Adapter Removal" on page 446.
14. Remove all power, signal, and SCSI cables from the PCI riser card.
