and then PCI-X slots 2 and 3. Then, the system starts (boots) the PCI and PCI-X devices in this order, if you have not changed the default boot precedence. Note: To change the boot precedence for PCI and PCI-X devices, you must disable the devices through the Configuration/Setup Utility program. Start the Configuration/Setup Utility program, and select Start Options from the main menu (see "Starting the Configuration/Setup Utility program" on page 11). Installing an adapter This section contains the procedure for installing a hot-plug or non-hot-plug PCI or PCI-X adapter. If your operating system supports hot-plug PCI or PCI-X adapters, you can replace a failing hot-plug PCI or PCI-X adapter with a new hot-plug PCI or PCI-X adapter of the same type without turning off power to the server. If your operating system and adapter also support the hot-add feature, you can install a new adapter without turning off the power to the server. Note: You do not have to turn off the server to install hot-plug adapters in the hot-plug slots. However, you must turn off the server when performing any steps that involve installing or removing cables. Important: Do not remove a hot-plug PCI or PCI-X adapter before performing the operating-system-defined procedure for disabling the Active PCI-X (hot-plug) slot that contains the adapter. Failure to do so might cause your system to lock up. See your operating-system documentation. The following illustration shows how to install a hot-plug PCI or PCI-X adapter. Chapter 4.

devices in this order, if you have not changed the default boot precedence.
Note:
To change the boot precedence for PCI and PCI-X devices, you must

Installing an adapter
This section contains the procedure for installing a hot-plug or non-hot-plug PCI or
PCI-X adapter. If your operating system supports hot-plug PCI or PCI-X adapters,
you can replace a failing hot-plug PCI or PCI-X adapter with a new hot-plug PCI or
PCI-X adapter of the same type without turning off power to the server. If your
operating system and adapter also support the hot-add feature, you can install a
new adapter without turning off the power to the server.
Note:
You do not have to turn off the server to install hot-plug adapters in the
hot-plug slots. However, you must turn off the server when performing any
steps that involve installing or removing cables.
Important:
Do not remove a hot-plug PCI or PCI-X adapter before performing the
operating-system-defined procedure for disabling the Active PCI-X (hot-plug) slot
that contains the adapter. Failure to do so might cause your system to lock up. See
your operating-system documentation.
The following illustration shows how to install a hot-plug PCI or PCI-X adapter.
