Configuring adapters
PCI devices automatically communicate with the server configuration information.
This usually results in automatic configuration of a PCI device. From the
Configuration/Setup Utility program, you can select available resources for the
adapter that you are installing. If a conflict does occur, see "Resolving
configuration conflicts" on page 32.
Refer to the documentation that comes with the adapter for information about
required system resources. Then, make the appropriate jumper or switch settings
on the adapter.
Installing a hot-plug PCI adapter
This section gives the procedure for installing a hot-plug PCI adapter. If you want
to remove a hot-plug adapter, reverse the steps. If your operating system supports
hot-plug PCI adapters, you can replace a failing hot-plug PCI adapter with a new
adapter of the same type without turning off power to the server.

Notes:
1. All expansion slots are hot-plug, 64-bit, PCI slots.
2. You can install:
a. A full-length or half-length, 32-bit or 64-bit, 5 V or Universal, hot-plug or non-hot-plug PCI
adapter in slots 1–5 or 10–12. 66 MHz PCI adapters plugged into these slots will operate
at 33 MHz.
b. A full-length or half-length, 32-bit or 64-bit, 3.3 V or Universal, hot-plug or non-hot-plug PCI
adapter in slots 6–7 and 8–9. A 33 MHz PCI adapter installed in one of these slots limits a
66 MHz PCI adapter installed on the same bus to 33 MHz.
3. To optimize performance, spread the installation of high-speed adapters, such as 66 MHz
Ethernet adapters, between the two 66 MHz PCI buses.
1. You do not need to turn off the server to install or remove a hot-plug PCI
adapter.
2. When you install an adapter, be sure that the gold-edge connectors on the
adapter match the connectors in the PCI slot.
