System Overview 1-3
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.
