System Overview 1-3
This server system is designed for minimum downtime. To this end, the server includes
or has the options to include the following:
„
Optional power system redundancy; in a system configured with two power supplies,
the system will continue to operate with a single power supply failure.
„
Self-contained power supply units that can be easily installed or removed from the
back of the chassis.
„
SCSI drive bays accessible from the front of the chassis.
„
Hot-swap SCSI disk drive backplane; a failed drive can be removed and a new drive
installed without system power being turned off, if an optional Redundant Array of
Independent Disks (RAID) controller is installed.
„
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.
„
Chassis that supports up to two power supplies. The second power supply can be
added to provide redundant power.
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, diskette drives and hard disk drives.
Your server features the following major components:
„
System board with one Pentium

II microprocessor. The system board has a
processor upgrade socket for an additional processor. The board may contain up to
two processors.
„
Single or dual high-performance Pentium II processors packaged in Single Edge
Connector (SEC or SECC2) cartridges.
„
System board supports 4 EDO DIMM devices for a minimum memory size of 32
MB; total is 512 MB.
„
System board has three ISA slots, two PCI slots, and one shared PCI\ISA slot for
add-in boards. The system board also has onboard external I/O (serial, parallel,
video) interfaces.
„
System board has two video memory upgrade sockets (512 KB each) containing an
additional 1 MB of video memory.
„
Chassis that holds up to 12 drives: seven hot-swap bays for ultra-2 (LVD) SCSI hard
drives; five removable media expansion bays with a CD-ROM reader already
installed in one bay; and a half-height bay with a diskette drive already installed in
the bay.
„
Seven hot-swap SCSI hard disk drive bays accessible from the front of the chassis.
The bays are secured behind a lockable front door where the drives can be swapped
in or out of the system without powering it down, if RAID is configured in the
system. (Tower models only.)
„
SCSI backplane is Ultra-2 (LVD) ready.
