9-6 Upgrading Your ServerDEVICE INSTALLATION OR REMOVAL PROCEDUREInstall or remove a component from the server in the following procedure.Hard Disk DriveThe server has six device bay slots to install hard disks with the SCA2 interface (Ultra 320 SCSI) inthe disk bay of the front of the server.IMPORTANT: Do not use any hard disks that are not authorized by NEC. Installinga third-party hard disk may cause a failure of the server as well asthe hard disk. Purchase hard disks of the following models:– N8150-161F (18.1 GB, 10,000 rpm, Ultra 320)– N8150-162F (36.3 GB, 10,000 rpm, Ultra 320)– N8150-163F (73.2 GB, 10,000 rpm, Ultra 320)– N8150-171F (146 GB, 10,000 rpm, Ultra 320)– N8150-164F (18.1 GB, 15,000 rpm, Ultra 320)– N8150-165F (36.3 GB, 15,000 rpm, Ultra 320)– N8150-172F (73.2 GB, 15,000 rpm, Ultra 320) To make array configuration, specify RAID0, RAID1, or RAID5 asthe RAID level. Up to six hard disk drives can be installed in standard mode. Ifusing the flex bay, you can install up to seven hard disk drives.All six slots may contain a hard disk approximately 25.4 mm (1 inch) high. The SCSI IDs of ID0through ID5 are always assigned to hard disks as shown below.The hard disk drive bays are connected to the SCSI connector on the mother board when the serveris shipped. To use the hard disk drives in a disk array configuration, run the SCSI BIOS utility (seeChapter 4). If you have an optional RAID controller, install it to your server and reconnect the cablefrom the connector on the mother board to the RAID controller connector. For the cablereconnection, see "Disk Array Controller".A dummy block is installed in the hard disk drive bays except the one with SCSI ID0 defined. Thepurpose of a dummy block is to increase the cooling effect in the server. Install a dummy block inslots not containing a hard disk drive.SCSI ID0SCSI ID1SCSI ID5 SCSI ID4SCSI ID3SCSI ID2
