• When you install any PCI adapter, the power cords must be disconnected from the power source before
you remove the PCI Express riser-card assembly and the PCI-X riser-card assembly. Otherwise, the active
power management event signal will be disabled by the system-board logic, and the Wake on LAN feature
might not work. However, after the server is powered-on locally, the active power manager active power
management event signal will be enabled by the system-board logic.
• If you switch the PCI adapter from slot 1 riser assembly to slot 2, you will need to remove the screw from
the standard bracket and then replace the standard bracket with the low-profile bracket.
• The server provides two PCI riser-card slots on the system board. A PCI riser assembly with a bracket is
installed in slot 2. The following information indicates the riser-card slots and the type of adapters that the
riser cards support:
– Standard models of the server come with two PCI Express riser-card assemblies installed. If you want
to replace them with PCI-X riser-card assemblies, you must order the PCI-X riser-card assembly
option, which includes the bracket.
– A PCI Express riser-card assembly has a black connector and supports PCI Express adapters, and a
PCI-X riser-card assembly has a white (light in color) connector and supports PCI-X adapters.
– PCI riser slot 1 (the farthest slot from the power supplies). This slot supports only low-profile adapters.
– PCI riser slot 2 (the closest slot to the power supplies). This slot supports only full-height, half-length
adapters. You must install a PCI riser-card assembly in slot 2 even if you do not install an adapter.
The following table lists the supported configurations for the PCI rise-cardr slots.

1. The instructions in this section apply to any PCI adapter (for example, video graphics adapters or
network adapters).

monitor. This is the highest resolution that is supported for any add-on video adapter that you install in
the server.
3. Any high-definition video-out connector or stereo connector on any add-on video adapter is not
supported.
To install an adapter, complete the following steps:
Step 1. Read the safety information that begins on
