9-10 Upgrading Your Server
3.5-inch Hard Disk
The 3.5-inch hard disk drive bay on the front of the server contains six slots on which hard disks can
be installed. The drive bay is not equipped with any hard disks (excluding when one or more built-
in hard disks are ordered). Purchase the hard disks additionally if required.
IMPORTANT:
 Do not use any hard disks not approved by NEC. If an unapproved
third party's hard disk is installed in the server, not only the hard
disk but also the server itself may be defected. Purchase hard disks
of the following models:
– N8150-162F (36.3GB, 10,000 rpm, Ultra320)
– N8150-163F (73.2GB, 10,000 rpm, Ultra320)
– N8150-171F (146GB, 10,000 rpm, Ultra320)
– N8150-165F (36.3GB, 15,000 rpm, Ultra320)
– N8150-172F (73.2GB, 15,000 rpm, Ultra320)
 For the disk array configuration, refer to the manual that comes with
the disk array controller.
A hard disk having the thickness of 1 inch can be installed on each of the slots. The SCSI IDs of
the slots are fixed to ID0 to ID5 from bottom to top.
In the configuration at the shipment, the cable on the 3.5-inch hard disk drive bay is connected to
the Ultra320 SCSI (A) connector on the mother board.
To provide the disk array configuration, connect the cable on the 3.5-inch hard disk drive bay to the
disk array controller. The SCSI standard of the hard disk to be added should be the same as that of
the existing disks.
A dummy tray is installed in an empty slot of the 3.5-inch hard disk drive bay. This is intended to
improve the cooling effect within the server. Always install a dummy tray in any slot in which a
hard disk is not installed.
IMPORTANT: A specified dummy tray must be used.
