Installing an adapter The following notes describe the types of adapters that the computer supports and other information that you might consider when installing an adapter. See "System board option connectors" on page 32 for an illustration of the adapter slot locations. v Read the documentation that comes with the operating system. v Locate the documentation that comes with the adapter and follow those instructions in addition to the instructions in this chapter. If you have to change the switch or jumper settings on the adapter, follow the instructions that come with the adapter. v The computer comes with the following adapter connectors, or slots: Important: The slot designation information describes the adapter that is supported in that slot and the bandwidth for that slot. For example, the x8 (x4) designation for slot 2 identifies an x8 slot that is designed to support x4 adapters and x8 adapters that can downshift to operate at the x4 bandwidth. If you install an x8 adapter in slot 2 that can downshift to the x4 bandwidth, it will run at the x4 bandwidth. The x8 connector is used for x4 and x8 adapters. - Slot 1, PCI Express x16 (x16) - Slot 2, PCI Express x8 (x4) Note: If you install a double-wide adapter in slot 1, it will overlap slot 2. Therefore, you will have one less PCI slot available in which you can install an adapter. To work around this, you can set jumper 10 on the system board to positions 2 and 3, and jumper 11 on the system board to positions 1 and 2 to reroute the signals of slot 2 down to slot 3. This converts slot 3 to a PCI Express x8 slot. For the locations of jumpers 10 and 11 on the system board, see the Problem Determination and Service Guide.

You can install up to five additional optional adapters in the computer. v You can install full-length adapters in PCI Express slots 1, 2, and 3. v You can install full-length 64-bit or 32-bit PCI-X adapters, or 32-bit 3.3 V PCI adapters in slots 4 and 5. v You can install a full-length 32-bit, 5 V PCI adapter in slot 6. v To assign system resources, the computer scans the adapters in the following sequence: - Slot 1, PCI Express x16 (x16) - Slot 2, PCI Express x8 (x4) - Slot 3, PCI Express x16 (x4) Chapter 4.
