v The adapter slots are on the riser-card assembly. You must first remove the

riser-card assembly to access the adapter slots.

v The two PCI Express slots on the riser-card assembly support PCI Express x8

1.0a adapters.

v You can install one full-height three-quarter-length adapter in expansion slot 1

and one low-profile half-length adapter in expansion slot 2.

v The optional Remote Supervisor Adapter II SlimLine can be installed only in the

dedicated connector on the system board (see “System-board optional-device

connectors” on page 6 for the location of the connector). To install the Remote

Supervisor Adapter II SlimLine, see “Installing a Remote Supervisor Adapter II

SlimLine” on page 17.

v The server uses a rotational interrupt technique to configure PCI Express

adapters so that you can install PCI Express adapters that do not support

sharing of interrupts.

v An optional ServeRAID

™

8s controller provides RAID level 5 support to the

hot-swap drives. A ServeRAID 8s controller supports the 2.5-inch hard disk drives

without modification. To use a ServeRAID 8s controller with hot-swap 3.5-inch

drives, you must connect it to the hard disk drive backplane with a SAS signal

cable that is 58 cm (22.8 in.) long. See http://www.ibm.com/servers/eserver/

serverproven/compat/us/ for information about ordering the cable.

v An optional IBM SAS HBA Controller adapter enables you to connect external

storage devices, such as SAS or SATA hard disk drives or tape drives, to a

simple-swap SATA model server.

v The server scans the PCI slots to assign system resources. The scan sequence

is related to the startup sequence. If you have not changed the default startup

sequence, the server scans the PCI slots in the following order: the integrated

Ethernet controllers 1 and 2; then, the drives connected to the SAS/SATA

controller; then, the PCI Express slots 1 and 2.
