Removing the riser-card assembly
The server comes with one riser-card assembly that contains two PCI Express x8
connectors. You can replace the riser-card assembly with one that contains two
PCI-X 64-bit 133 MHz connectors that support single-width IXA adapters.
To remove the riser-card assembly, complete the following steps.

to the dc power supply. See the documentation that comes with each dc power
supply.
