Working with adapters
Your server comes with adapter connectors or slots . The standard video adapter is
installed in mini-PCI slot 6 (PCI6). You can install up to five additional optional
adapters in PCI slot 1 (PCI1) and PCI-X slots 2 through 5 (PCI2 through PCI5).
See “System board” on page 34 for the locations of expansion slots on the system
board.
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
instructions in addition to the instructions in this chapter. If you need to change
the switch or jumper settings on your adapter, follow the instructions that come
with the adapter.
v
Installation of an AGP video adapter in the AGP slot is not supported.
v
You can install a only 32-bit adapter in the 32-bit PCI slot 1 and 64-bit adapters
in the 64-bit PCI-X slots 2 through 5.
v
You can install full-length adapters in all five expansion slots; however,
double-width adapters will not fit in slot 5 and are not supported. None of the
expansion slots are hot-plug.
v The 32-bit PCI slot 1 supports 5.0 V signaling PCI adapters; it does not support
3.3 V signaling adapters or 64-bit adapters.
v
The 64-bit PCI-X slots 2 through 5 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:
– The 32-bit PCI slot 1 and mini-PCI slot 6 (video adapter) are on the 33 MHz
PCI bus.
Note: Do not install any adapters other than the standard video adapter in
mini-PCI slot 6. Other adapter types are not supported.
– The 64-bit PCI-X slots 2 and 3 and the integrated Ethernet controller are on
the 100 MHz PCI-X bus, channel A.
– The 64-bit PCI-X slots 4 and 5 and the integrated SCSI controller with RAID
capabilities are on the 100 MHz PCI bus, channel B. If an optional
ServeRAID-5i controller is installed, it overrides the standard functionality of
the integrated SCSI controller with RAID capabilities and forces PCI-X slots 4
and 5 to 66 MHz.
v
The optional IBM Remote Supervisor Adapter can be installed only in PCI slot 1.
Use the ribbon cable that comes with this adapter to connect it to the Remote
Supervisor Adapter connector (JMGT1) on the system board.
v
The optional ServeRAID-5i controller can be installed only in PCI-X slot 4 and
must use the 3-U bracket that comes preinstalled on the controller.
v To provide failover protection, an optional Ethernet adapter can be installed only
in PCI-X slots 2 through 5.
v
The server scans the AGP slot, mini-PCI slot 6, PCI expansion slot 1, and PCI-X
expansion slots 2 through 5 to assign system resources. Then, the server starts
the PCI devices in the following order, if you have not changed the default
startup sequence: AGP slot, mini-PCI slot 6, PCI expansion slot 1, system-board
integrated drive electronics (IDE) or SCSI devices (including optional
ServeRAID-5i controller), and then PCI-X expansion slots 2 through 5.
