1 Non-hot-plug PCI slots 1-2 (on PCI bus A) (3.3 volt) 2 Hot-plug PCI slots 3-6 (on PCI bus B) 3 Power LEDs for hot-plug slots 4 Internal Attention LEDs for hot-plug slots 5 External Attention LEDs for hot-plug slots Adapter considerations Before you continue with the adapter-installation procedure: • Review 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 the adapter, follow the instructions that come with the adapter documentation. • Slots 3 through 6 support 5.0V, 3.3V, and universal PCI adapters. Note: Universal PCI adapters support both 3.3 V and 5.0 V operation. • Slots 1 and 2 support 3.3 V and universal non-hot-swap PCI adapters only. • 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. • The system scans PCI slots 1 through 6 to assign system resources; then the system starts (boots) the PCI devices in the following order: processor board devices, slots 1 and 2, and then slots 3 through 6. • The performance of the PCI adapters depends on the types of adapters in the system. Installing a hot-plug adapter Refer to the following illustration to install a hot-plug PCI adapter. Note: The illustrations in this book may be slightly different from your server.
