1-2 System Overview
Overview
Your server is a modular, multiprocessing server based on the IntelPentium® III
microprocessor family. It is a solid performer and offers the latest technology. The
combination of compute performance, memory capacity, and integrated I/O provides a
high performance environment for many server market applications. These range from
large corporations supporting remote offices to small companies looking to obtain basic
connectivity capability such as file and print services, e -mail, web access, web site
server, etc.
Your server is housed and available as a rack-mount system. Your server conveniently
installs into a standard EIA 19-inch rack assembly. See Figure 1-1.
Figure 1-1. Rack-Mount System Front View
Your server includes a 3.5” diskette drive, a CD-ROM drive and five hot-swap SCSI
hard disk drive bays. The hot-swap SCSI hard disk drive bays support up to five 1.0-
inch SCSI hard disk drives that can be swapped in or out of the system without
powering it down, if RAID functionality is configured in the system.
Alternately, your server can be configured to include a 5.25” removable media device
bay. This configuration includes a 3.5” diskette drive, a CD-ROM drive, a 5.25”
removable media drive bay, and four hot-swap SCSI hard disk drive bays. The
removable media drive bay may be used for installation of a high-speed tape drive.

System Overview 1-3
As application requirements increase, you can expand your server with an additional
processor, additional memory, add-in boards and peripheral devices: tape devices,
CD-ROM, and hard disk drives.
Your server features the following major components:
!Single or dual high-performance Pentium III processors.
!64 MB to 4 GB of memory, using up to four DIMMs.
!Three 64-bit/33Mhz PCI expansion slots and one 32-bit/33Mhz PCI expansion
slot for add-in boards.
!Embedded PC-compatible support (serial, parallel, mouse, keyboard, diskette,
USB, LAN, and video).
!Integrated onboard ATI RAGE IIC Super Video Graphics Array (SVGA)
controller with 4 MB of video memory.
!Adaptec AIC7899 SCSI controller providing Wide Ultra2 and Ultra-160/M SCSI
interfaces.
!Integrated onboard Network Interface Controller (NIC), an Intel 82559 PCI LAN
controller for 10 or 100 Mbps Fast Ethernet networks with an RJ-45 Ethernet
connector.
!Single Channel enhanced IDE controller.
!A slim design CD-ROM drive and 3 ½-inch diskette drive installed in a single
bay.
!Integrated dual Universal Serial Bus (USB) ports.
!Hardware monitors (temperature, fans, and voltage) and software monitors to
indicate failures.
!Redundant cooling fans.
!A 330-watt power supply; a second optional 330-watt hot-swap redundant power
supply is available for your server.
!Keylocked front cover, including an intrusion switch.
Hot-Swap SCSI Hard Drive Bays
!Five hot-swap 1.0-inch SCSI hard disk drive bays accessible from the front of
the chassis can be swapped in or out of the system without powering it down if
RAID is configured in the system.
!High degree of SCSI disk fault tolerance and advanced disk array management
features through the use of RAID technology, if an optional RAID controller is
installed.
!SCSI controller, cables, backplane and devices are Ultra160/M ready.

System Overview 1-5
Power Supplies
The system contains one auto-sensing 330 watt power supply at an operating frequency
of 50/60 Hz. A second optional power supply may be added as part of a fault-tolerant
hot-swap design. With two power supplies installed, in the unlikely event of a power
supply failure, the load is transferred to the remaining power supply without
interruption to normal operation. In this case the faulty power supply can be replaced
without powering down the system.
Note: The power supplies are not hot swappable unless there
are two supplies installed.
The power supplies are designed to comply with existing emission standards and
provide sufficient power for a fully loaded system configuration.
Peripheral Bays
Your server supports a variety of standard PC AT-compatible peripheral devices. The
chassis includes these peripheral bays:
!A 3.5-inch front panel bay for mounting the standard 3.5" diskette drive
(supports 720 KB and 1.44 MB diskette media)
!A standard CD-ROM drive bay
!An optional 5.25-inch removable media front panel bay for mounting a half-
height 5.25-inch peripheral device such as an optional tape drives
!Depending on your configuration, your server includes either four or five hot-
swap SCSI hard disk drive bays for mounting hard disk drives installed in easily
removable drive carriers.
Note: The hot-swap SCSI hard disk drive bays contain a hot-
swap back plane that require an 80-pin single connector attachment
(SCA) connector on the drives that you install.

1-6 System Overview
SAF-TE Logic
Note: SAF-TE Logic is in systems that include the hot-swap
SCSI disk drive cage. SAF-TE Logic is not available in systems that
include the standard SCSI disk drive cage.
The SCSI backplane includes SAF-TE (SCSI Accessed Fault Tolerant Enclosure) logic
that provides an interface to the disk subsystem that supports status signals, hot
swapping drives, and enclosure monitoring.
The transport mechanism for the standardized alert detection and status reporting is the
SCSI bus. Disk drives, power supplies, cooling fans, and temperature are continually
monitored and the conditions then reported over the SCSI bus to the system. When used
with RAID management software the user can be alerted of impending or imminent
disk conditions requiring attention. This allows the user to react to conditions that could
normally go unnoticed until data loss.
