Hard Disk Drive - NEC EXPRESS5800/120Re-2 Service Manual

Hard Disk Drive

The server has seven hard disk drive slots to install hard disks with the SCA2
interface (Ultra 160 SCSI.) Up to six hard disk drives can be installed in the
standard configuration. If using the flex bay to install a hard disk, you can install
up to seven hard disk drives in the server.
All seven slots may contain a hard disk approximately 25.4 mm (1 inch) high.
The SCSI IDs of ID0 through ID5 are always assigned to hard disks as shown in
Figure 4-53.

In the standard configuration hard disk drive bays are connected to the SCSI
connector on the system board when the server is shipped. To use the hard disk
drives in a disk array configuration, reconnect the cable from the connector on
the system board to the disk array controller connector. For the cable
reconnection, see "Disk Array Controller".
A dummy tray is installed in all unpopulated hard disk drive bays. The purpose
of a dummy tray is to ensure the cooling effect in the server. Always install a
dummy tray in slots not containing a hard disk drive.
