This server system 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:
Two self-contained power supplies that provide redundant power (i.e., the system
!
will continue to operate with a single power supply failure) and are hot swappable.
The two power supplies are easily installed or removed from the back of the chassis
without turning the system power off.
Cooling system redundancy where the system will continue to operate in the event of
!
a fan failure and the redundant fans will switch to maximum operating speed.
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 4 MB of video memory (occupies one
!
PCI slot per PCI module).
SCSI disk adapter providing dual channel Ultra 160 SCSI interfaces for the hot swap
!
hard disk drives.
Embedded single channel enhanced IDE adapter providing interface for peripheral
!
devices (CD-ROM and super floppy disk drive).
Integrated onboard Network Interface Controller (NIC), an Intel 82559 PCI LAN
!
adapter for 10 or 100 Mbps Ethernet networks with a RJ-45 Ethernet connector.
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 and mouse.
Hardware monitors (temperature, fans, and voltage) and software monitors to
!
indicate failures.
Hardware monitors (temperature and voltage) and software monitors to indicate
!
failures.
Easy access to all parts for service.
