B digital device, pursuant to Part 15 of FCC rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation.
This equipment generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio and
television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and receiver
• Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected
• Consult the dealer or an experienced radio/TV technician for help

This device complies with Part 15 of the FCC rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference, and, (2) this device must
accept any interference received, including interference that may cause undesired operation.

Chapter 1
Overview
The AlphaServer 800 system is a high-performance, uniprocessor system intended
for use as a local area network (LAN) server or commercial applications server.
Ideal uses for the AlphaServer 800 system include the following:
• Application server−To run applications such as relational databases, electronic
mail, and communications
• Print server−To provide printing resources to PCs and other systems in a LAN
• File server−To provide disk storage to PCs and other systems in a LAN
• Compute server−To enable PCs to remotely run computation-intensive
applications
• Replicated site server−To operate in commercial applications due to remote
management features
This chapter provides an overview of the system. Sections are:
• System Architecture
• System Features
• System Parts
• Control Panel
• Rear Panel Connections
• Storage Device LEDs
• Console
• System Options
• System Specifications
• Acoustical Data

1.1 System Architecture
The AlphaServer 800 system is a low-end server that offers PCI and EISA bus
options on a single system board. Figure 1-1 shows the architecture of the
system.

Overview 1-3
The AlphaServer 800 system is housed in an enclosure containing the motherboard,
CPU daughter card, other logic modules, and power supply with internal fans. The
enclosure allows for up to four internal mass-storage devices, with up to four
removable media devices, one of which is a 3.5-inch floppy drive. The control panel
includes Halt, Reset, and On/Off buttons. The system can be used as a deskside
pedestal in the vertical position, or, with the addition of brackets, may be mounted in
the horizontal position in a standard 19-inch rack.
All memory and I/O components are on a single system board that contains the
memory subsystem, the PCI bus, the EISA I/O bus, the integrated system I/O
controllers, and option slots for PCI-based and EISA-based option cards. A server
management corner on the system board serves to monitor/control the system
remotely.
The CPU daughter card interfaces to the motherboard with a 600-pin connector.
It is based on a 21164 microprocessor that is a superscalar, super-pipelined
implementation of the Alpha architecture and runs at an optimized price/
performance speed of 300 to 500 MHz. The chip contains two 8-Kbyte, direct-
mapped primary caches and a 96-Kbyte, 3-way set-associative secondary cache. The
CPU card uses a 2-Mbyte, direct-mapped, writeback B-cache. The B-cache is 16
bytes wide with a block size of 64 bytes.
