Upgrading Your Server 9-7
SCSI ID / SAS Port
The hard disk drive bay may contain up to six hard disk drives. The SCSI IDs or SAS port numbers
are factory-assigned to hard disk drives as shown below.
The hard disk drive bays are connected to the SCSI connector on the mother board when the server
is shipped. To use the hard disk drives in a disk array configuration, run the SCSI BIOS utility (see
Chapter 4). If you have an optional RAID controller, install it to your server and reconnect the cable
from the connector on the mother board to the RAID controller connector. For the cable
reconnection, see "Disk Array Controller".
A dummy block is installed in the hard disk drive bays except the one with SCSI ID0 or SAS Port 0
defined. The purpose of a dummy block is to increase the cooling effect in the server. Install a
dummy block in slots not containing a hard disk drive.
