NEC 320Lb-R manual System Overview

This server is designed for full redundancy and hot plug replacement of all major subsystems. The system modules that can be replaced are identified as Customer Replaceable Units (CRUs) of which most are redundant and hot pluggable. To this end, the server includes or has the option to include the following:

!SCSI hard disk drive bays accessible from the front of the chassis.

!Hot-swap SCSI disk drive backplane; a failed drive can be removed and replaced with a new drive without system power being turned off.

!High degree of SCSI disk fault tolerance and advanced disk array management features.

!Video Graphics Array (VGA) controller with 2 MB of video memory (occupies one PCI slot per PCI module).

!SCSI disk adapter providing Ultra 160 SCSI interface for the hot swap hard disk drives.

!Embedded single channel enhanced IDE adapter providing interface for a peripheral device (CD-ROM drive).

!Integrated Network Interface Controller (NIC), supporting 10Base-T/100Base- TX/1000Base-T network systems.

!Storage module that holds up to six hot-swap SCSI hard disk drives (three logical disks).

!SCSI backpanel is Ultra2 capable.

!Integrated dual Universal Serial Bus (USB) ports that include support for the keyboard, mouse, and a USB floppy diskette drive.

!Hardware monitors (temperature, fans, and voltage) and software monitors to indicate failures.

!Easy access to all parts for service.
