Device Installation Or Removal Procedure; Hard Disk Drive - NEC Express5800/120Rd-2 Service Manual

7-6 Disassembly and Reassembly

DEVICE INSTALLATION OR REMOVAL PROCEDURE

Install or remove a component from the server using the following procedure.

Hard Disk Drive

The server has seven device bay slots in the disk bay of the front of the server 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 below.
SCSI ID0
SCSI ID1
SCSI ID2
*The figure shows the SCSI IDs when the flex bay contains a hard disk drive instead of the floppy disk or CD-ROM
drive.
The 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 the hard disk drive bays except the one with SCSI ID0 defined. The
purpose of a dummy tray is to increase the cooling effect in the server. Always install a dummy
tray in slots not containing a hard disk drive.
SCSI ID3
SCSI ID4
SCSI ID5
