System Overview 1-3
Enclosure
The system is housed in an enclosure containing the system board, other logic
modules, and two power supplies (maximum of three) with internal fans. The
enclosure has bays for internal mass-storage devices, including a combination
IDE CD-ROM/floppy disk drive, one available half-height removable bay, and
either four 1.6-inch or six
1-inch hot-swap drive bays. An operator control panel includes Power, Reset,
and Halt buttons
The system can be used as a desk-side pedestal in the vertical position, or with
the addition of brackets, can be mounted in the horizontal position in a
standard rack.
Common Components
The basic building block of the system is the chassis, which houses the following
common components:
• Up to two CPUs, based on the 21264 Alpha chip
• Up to 16, 200-pin memory DIMMs
• ive 64-bit PCI slots and one shared 32-bit ISA or 64-bit PCI slot
• A removable media bay that accommodates one 5-25-inch slim- height
CD/floppy disk combination drive and one 5.25-inch half- height tape device
• One storage disk cage that houses four 1.6-inch drives or a cage that houses
six 1.0-inch drives
• Two 375-watt power supplies and a bay for a third supply for redundancy
• Two serial ports and one parallel port for external options
• An operator control panel with a Power button, Halt button, and Reset
button, and diagnostic LEDs
