Installing an adapter
The following notes describe the types of adapters that the server supports and
other information that you must consider when you install an adapter:

instructions in addition to the instructions in this section. If you have to change
switch settings or jumper settings on the adapter, follow the instructions that
come with the adapter.

v The adapter slots are on the riser-card assembly. You must first remove the

riser-card assembly to access the adapter slots.

and one low-profile half-length adapter in expansion slot 2.

Note: When the optional Remote Supervisor Adapter II SlimLine is installed in

the server, you can install only a half-length adapter in expansion slot 1.
v If you have installed an optional PCI-X riser-card assembly in the server, you can
install a full-height, three-quarter-length PCI-X 64/133 MHz adapter in the PCI-X
slot on the riser-card assembly.
