IBM eServer xSeries 440 Installation Manual page 25

ServeRAID adapter, see the ServeRAID documentation and the cabling information in
this section to install the ServeRAID adapter.
Servers that do not come with an IBM ServeRAID adapter installed come with two
SCSI cables:
• One end of the first SCSI cable is attached to the connector on the SCSI
backplane, and the other end is attached to the connector for the integrated SCSI
controller behind fans 3 and 4.
• The second SCSI cable is preinstalled along the inside of the server and both
ends are loose inside the server. When you install a ServeRAID adapter, you will
connect this cable to the adapter and to the SCSI backplane.
The following procedure describes the internal cabling needed to install a ServeRAID
adapter.
Important: When installing multiple ServeRAID adapters in a server that has the PCI-
X slot enabled for high scan (boot) priority, ensure that the ServeRAID adapter
controlling the startup (boot) drive is installed in a PCI slot that is scanned before the
PCI slots that contain the other ServeRAID adapters. See "PCI and PCI-X adapter
considerations" on page 10.
Complete the following steps to cable the ServeRAID adapter.
1. Review the information in "Safety" on page v, "Before you begin" on page 5, and
"Handling static-sensitive devices" on page 6.
2. Turn off the server and disconnect all power cords and external cables; then, open
the server cover (see "Opening the cover" on page 9).
3. Remove fans 3 and 4, which are located just behind the PCI-X slots (see the
illustration on page 5 for the location of the fans).
4. Disconnect the short SCSI cable from the SCSI backplane and the integrated
SCSI controller; then, store this short cable in a safe place for future use.
5. Install the ServeRAID adapter in a PCI-X slot (see "Installing adapters" on page
11).

6. Locate the preinstalled SCSI cable; then, attach a connector on the cable to the
ServeRAID adapter.
7. Locate the connector on the opposite end of the SCSI cable and connect it to the
SCSI backplane connector.
