Adapter considerations
Before you install an adapter, review the following information:
v Read the documentation that comes with your operating system.
v Locate the documentation that comes with the adapter and follow those
v You can install only low-profile adapters in slots 1 and 2.
v You can install standard full-length adapters, with the adapter guides removed
v You can install only a half-length adapter in slot 5.
v The ServeRAID-5i controller can be installed only in PCI slot 2. The low-profile
v The optional IBM Remote Supervisor Adapter can be installed only in PCI slot 5.
v Your server supports 5.0 V and universal PCI adapters on the 32-bit PCI slot 5;
v The PCI bus configuration is:
v The system scans PCI and PCI-X slots 1 through 5 to assign system resources;

from the adapters, in slots 3 and 4.
2-U bracket that comes with the controller is required to install the controller.
Use the ribbon cable that comes with the adapter to connect the adapter to the
system management connector on the PCI riser-card.
your server supports only 3.3 V and universal PCI adapters in the 64-bit
PCI/PCI-X slot 3 and 4.
– Non-hot-plug, 64-bit PCI-X slots 1 through 2 (PCI bus A, 100 MHz)
– Non-hot-plug, 64-bit PCI-X slots 3 through 4 (PCI bus B, 133 MHz)
– Non-hot-plug, 32-bit PCI slot 5 (PCI bus C, 33 MHz)
then the system starts (boots) the system devices in the following order, if you
have not changed the default boot precedence: integrated Ethernet controller,
integrated SCSI controller, and then PCI and PCI-X slots 5, 3, 4, 1, and 2.
Notes:
1. Some models come with the ServeRAID-5i controller preinstalled.
2. If the ServeRAID-5i controller is installed, it takes control of the integrated
SCSI controller with RAID capabilities and operates at 66 MHz. The
ServeRAID-5i controller can be installed only in slot 2.
3. 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.
