Replacing an adapterThe following notes describe the types of adapters that the server supports andother information that you must consider when you replace an adapter:v To confirm that the server supports the adapter that you are installing, seehttp://www.ibm.com/systems/info/x86servers/serverproven/compat/us/.v Locate the documentation that comes with the adapter and follow thoseinstructions in addition to the instructions in this section.v Do not set the maximum digital video adapter resolution above 1280 x 1024 at75 Hz for an LCD monitor. This is the highest resolution that is supported forany add-on video adapter that you install in the server.v Avoid touching the components and gold-edge connectors on the adapter.v Any high-definition video-out connector or stereo connector on any add-onvideo adapter is not supported.v The server uses a rotational interrupt technique to configure PCI adapters sothat you can install PCI adapters that do not support sharing of PCI interrupts.v The server provides two PCI riser slots on the system board. The riser cardsprovide up to three PCI Express Gen2 adapter slots. The following table lists thePCI-e slots on the riser-card and the system board, the microprocessor to whicheach slot is connected, and the supported adapters that you can install in eachslot:Table 23.

Do not install any internal RAID adapter in PCI riser-card assembly 1.v The following table lists the option part numbers and CRU part numbers for thenetwork adapters.Table 24.
