Working with adapters The server comes with adapter connectors, called slots. The AGP video adapter is installed in the AGP slot. You can install up to five PCI adapters in PCI slots 1 through 5. All PCI expansion slots are 32-bit, 33 MHz slots. Note: The illustrations in this document might differ slightly from your hardware. The following illustration shows the location of the system expansion slots on the system and PCI extender boards. AGP slot PCI slot 1 PCI slot 2 PCI slot 3 PCI slot 4 PCI slot 5 Adapter considerations Before you install an adapter, review the following: v Locate the documentation that comes with the adapter and follow those instructions in addition to the instructions given in this chapter. If you need to change the switch or jumper settings on your adapter, follow the instructions that come with the adapter. v You can install full-length adapters in all five PCI expansion slots. v The server supports 5.0 V and universal PCI adapters; it does not support 3.3 V adapters. v The server uses a rotational interrupt technique to configure PCI adapters. Because of this technique, you can install a variety of PCI adapters that currently do not support sharing of PCI interrupts. v If you are installing or replacing an adapter that will control your startup (boot) drive, install the adapter in PCI expansion slot 2. v PCI expansion slots 1 through 5 are on PCI bus 0. The system scans the AGP slot and PCI expansion slots 1 through 5 to assign system resources; then, the system starts (boots) the PCI devices in the following order, if you have not 46 xSeries 200 Type 8479 and xSeries 200VL Type 8481: Hardware Maintenance Manual
