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.

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
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.
