Installing adapters

The Active PCI-X slots in your server must be disabled by the operating system before
you insert or remove a PCI or PCI-X adapter.
Note: Before hot-swapping any of the PCI-X adapters, read the information in
Complete the following steps to install an adapter:
1. Review the information in "Safety" on page v, "Before you begin" on page 5,
2. Open the top cover.
You can use the Configuration/Setup Utility program to change the sequence and
have the server scan one of the first six PCI slots before it scans the integrated
devices. You cannot change the scan sequence of the PCI slots in an RXE-100
enclosure.
You can install both PCI and PCI-X adapters in the same bus. However, if you
install a PCI adapter and a PCI-X adapter in the same bus, the PCI-X features of
the PCI-X adapter will be disabled and the adapter will function as a PCI adapter.
You can install PCI or PCI-X adapters of speeds faster than what is labeled for a
particular PCI-X bus. For example, if you install two 133 MHz adapters into slots
that are labeled as 100 MHz slots, the adapters will operate at 100MHz.
If you install a 33 MHz and a 66 MHz adapter in the same bus, the bus speed will
match that of the slowest adapter.
If a single 133 MHz adapter is installed in PCI-X Bus B (slot 3 and 4), and the
other slot in PCI-X Bus B is empty, the adapter will operate at 133 MHz.
Your server supports six hot-plug 64-bit adapters in the expansion slots located on
the PCI-X board.
Note: You can add up to 12 additional PCI-X slots to your server by connecting
your server to a remote I/O expansion enclosure. For more information
about the expansion enclosure and how to connect your server to it, see
the documentation that comes with your expansion enclosure.
Your server supports 3.3 V adapters; it does not support 5.0 V adapters.

"Working inside the server with power on" on page 6, and "Handling static-
sensitive devices" on page 6.
Note: Inside your server there are six PCI-X slots: two 66 MHz, two 100 MHz,
and two 133 MHz. Before attempting to install a new adapter, be sure that
there is an available slot for it. If you need additional PCI-X slots, you can
purchase a remote I/O expansion enclosure either from your IBM
marketing representative or authorized reseller.
