Installing or replacing an adapter
The following notes describe the types of adapters that the server supports and
other information that you must consider when installing an adapter:
v
Locate the documentation that comes with the adapter and follow those
instructions in addition to the instructions in this section. If you must change the
switch or jumper settings on the adapter, follow the instructions that come with
the adapter.
v
Avoid touching the components and gold-edge connectors on the adapter.
v You can install full-length adapters and non-hot-plug adapters in slots 4 and 5.
v
A full-length adapter cannot be installed in slot 1 if the ServeRAID-7k option is
installed.
v The hot-plug slot (slot 6) supports full and half-length hot-plug and non-hot-plug
adapters. The hot-plug feature is operating system dependant. See the
documentation that comes with your operating system to see if it supports this
feature.
v
The 32-bit PCI slot (slot 1) supports 5.0 V and 3.3 V PCI adapters, with the
exception that you cannot install a long adapter in slot 1 on servers with
ServeRAID-7k installed.
v
The 64-bit PCI-X slots 4 through 6 support 3.3 V signaling PCI or PCI-X
adapters; they do not support 5.0 V signaling adapters.
v The PCI bus configuration is as follows:
– Non-hot-plug, 33 MHz 32-bit PCI slot 1 is on PCI bus A.
– Non-hot-plug, 64-bit PCI Express x4 slot 2 is on PCI bus B (independent of
slots 1, 3, 4, 5, and 6).
– Non-hot-plug, 64-bit PCI Express x4 slot 3 is on PCI bus C (independent of
slots 1, 2, 4, 5, and 6).
– Non-hot-plug, 100 MHz 64-bit PCI-X slots 4 and 5 and the integrated SCSI
controller with RAID capabilities are on PCI bus D.
– Hot-plug, 133 MHz 64-bit PCI-X slot 6 is on PCI bus F.
Note: If an optional ServeRAID controller is installed, it overrides the standard
functionality of the integrated SCSI controller with RAID capabilities. The
ServeRAID controller must be installed in its dedicated connector on the system
board.
v
The system scans PCI and PCI-X slots 1 through 6 to assign system resources.
The system then starts (boots) the system devices in the following order, if you
have not changed the default boot precedence: integrated Ethernet controller,
integrated SCSI controller with RAID capabilities, and then PCI and PCI-X slots 1
through 6.
Note: To change the boot precedence for PCI and PCI-X devices, start the
Configuration/Setup Utility program and select Start Options from the main
menu. See the User’s Guide on the IBM xSeries Documentation CD for details
about using the Configuration/Setup Utility program.
v
The server uses a rotational interrupt technique to configure PCI adapters so that
you can install PCI adapters that do not support sharing of PCI interrupts.
Complete the following steps to install or replace an adapter:
Note: If you are installing a hot-plug adapter go to “Installing or replacing a
hot-plug adapter (slot 6)” on page 29.
