FCC CLASSIFICATION
There are many variants of AlphaStation 500 Series systems. Your AlphaStation 500
Series system may be classified as either a Class A or a Class B FCC/EMC device,
depending upon its options and configuration.. To determine your system’s classification,
look at the FCC Classification Label on the bottom of the system.
FCC NOTICE -- CLASS A DEVICE
The equipment described in this manual generates, uses, and may emit radio frequency
energy. The equipment has been type tested and found to comply with the limits for a
Class A digital device pursuant to part 15 of FCC Rules, which are designed to provide
reasonable protection against such radio frequency interference.
Operation of this equipment in a residential area may cause interference, in which case the
user at their own expense will be required to take whatever measures are required to
correct the interference. If shielded cables have been supplied or specified, they must be
used on the system in order to maintain international regulatory compliance.
FCC NOTICE -- CLASS B DEVICE
This device complies with Part 15 of the FCC rules. Operation is subject to the following
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.
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. Any
changes or modifications to this equipment may void the user's authority to operate this
equipment.

FCC NOTICE -- CLASS B DEVICE (continued)
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 or
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 the receiver is connected.
• 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.
The keyboard and video ports should be connected only with shielded data cables with an
external ferrite bead over the cable. When either of these ports is connected with cables
without such a ferrite bead, the additional ferrite beads shall be clamped over these cables
next to the cable connector.

System Overview
Introduction
Congratulations on your purchase of the AlphaStation 500 Series System. The
AlphaStation 500 Engineering team is very proud of this product and you can be assured
that this machine has been designed and tested with the utmost attention to performance
and reliability. It can run OpenVMS, Digital UNIX, or Windows NT. Your machine’s
performance range can be extended by the addition of memory, PCI cards, video upgrades,
and hard disk drives.
The AlphaStation 500 Series is a high-performance system that uses the latest
microprocessor technology. The system can stand alone or function as a client in an office
network environment. This chapter describes the AlphaStation 500 Series system hardware
components, including the peripheral component interconnect (PCI) architecture, the
keyboard, the system unit front panel, and the system unit rear panel.
Following the information provided here will assure safe and proper operation of your
AlphaStation 500 Series System.

System Overview
1-2 AlphaStation 500 Series User Information
System Unit
Your AlphaStation 500 Series system uses a high-performance Alpha architecture CPU.
The system unit includes:
• Two accessible I/O bays: one for 3.5 inch x 1 inch floppy disk or 3.5 inch tape devices
and one for 5.25 inch x 1.6 inch CD-ROM
• Two non-accessible I/O bays: one that can accommodate a single 3.5 inch x 1.6 inch
device or two 3.5 x 1 inch devices. The bay below the floppy drive will accommodate
a single 3.5 inch x 1.6 inch hard drive (not available with tape option).
• Diskette controller that supports one diskette drive
• Integrated PCI-based SCSI-2 controller with Direct Memory Access and external
SCSI-2 connector that supports up to five SCSI devices. Initial offerings of the
AlphaStation 500 support Fast/Wide 10Mb/sec SCSI which will be phased into
Fast/Wide 20 Mb/sec SCSI.
• ThinWire or twisted-pair Ethernet ports.
• Four expansion slots - one for 64-bit PCI options; three slots for 32-bit PCI options.
• Eight industry standard DIMM connectors for a maximum of 1 GB.
