The FCC wants you to know...
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 made to this equipment may void the user's authority
to operate this equipment.
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 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
All external cables connecting to this basic unit need to be shielded. For cables
connecting to option cards, see the option manual or installation instructions.
This digital apparatus does not exceed the Class B limits for radio noise emissions
set out in the radio interference regulations of the Canadian Department of
Communications.

This equipment is in the 2nd Class category (information equipment to be used in a
residential area or an adjacent area thereto) and conforms to the standards set by
the Voluntary Control Council For Interference by Data Processing Equipment and
Electronic Office Machines aimed at preventing radio interference in such residential
area.
When used near a radio or TV receiver, it may become the cause of radio
interference.
Read the instructions for correct handling.
This equipment meets or exceeds requirements for safety in the U.S. (UL 1950),
Canada (CSA C22.2 No. 950), and Europe (EN 60950/IEC 950) with Nordic
requirements.
This equipment meets or exceeds the ergonomic requirements of ZH1/618 and is
certified to bear the GS mark by TUV Rheinland of Germany.
This equipment has been tested for radio frequency emissions and has been verified
to meet VDE 0871 Class B.
Laser Safety Notice
All CD-ROM drives included in DIGITAL computers are classified as Class 1 laser
products and comply with safety standards as set by U.S. government and applicable
European agencies.
No hazardous radiation is emitted from this CD-ROM drive; the laser beam is
completely enclosed in the CD-ROM subassembly during all customer operations
and maintenance. In the event that repair or service of the CD-ROM subassembly is
required, only authorized Digital service personnel should perform such repairs.

DIGITAL Server 5220
Preface P
This Service Maintenance Manual is a troubleshooting guide that can be used for
reference when servicing DIGITAL Servers.
DIGITAL reserves the right to make changes to this
Service Maintenance Manual
without notice. Accordingly, the illustrations and procedures in this document might
not apply to all DIGITAL Servers to be serviced since many of the diagnostic tests
are designed to test more than one product.
CAUTION: DIGITAL recommends that only A+/DIGITAL
Server certified engineers attempt to repair this equipment.
All troubleshooting and repair procedures are detailed to
support subassembly/module level exchange. Because of the
complexity of the individual boards and subassemblies, no
one should attempt to make repairs at the component level or
make modifications to any printed circuit board. Improper
repairs can create a safety hazard. Any indications of
component replacement or circuit board modifications might
void any warranty or exchange allowances.

Server Configurations
The following rules apply when Product Family Names and Product Model Names
are assigned to DIGITAL Server products. These rules apply to all products
developed in the NT Server Business Unit (NTSBU).
Server Naming Guidelines
• All products in a family carry the same name on the nameplate. (i.e. all
products in the Entry space will carry the name DIGITAL SERVER 500)
Family Name Segment
DIGITAL SERVER 500 ENTRY
DIGITAL SERVER 1000 WORKGROUP
DIGITAL SERVER 3000 DEPARTMENT
DIGITAL SERVER 5000 APPLICATION
DIGITAL SERVER 7000 ENTERPRISE
DIGITAL SERVER 9000 SUPER ENTERPRISE
• Product models within a family will be differentiated by the Product Model
Name. The Product Model Name will appear on a label on the rear of the
product. Specific configurations within a model will carry the same Product
Model Name and will be differentiated by the FR part number.

Product Model Numbering Convention
The following example describes the product model numbering convention:
DIGITAL SERVER 1234 5678 R
1 = PRODUCT FAMILY NAME (first character of family number)
2 = MAJOR PROCESSOR TECHNOLOGY DIFFERENTIATOR WITHIN THE
FAMILY.
This number will be assigned to each new platform based on the following matrix.
Open numbers will be assigned as new processor technology is introduced. THIS
FIELD IS NOT USED FOR SUB ENTRY PRODUCTS.
100 = Pentium Pro
200 = Pentium II – Slot 1
300 = EV5
400 = Pentium II – Slot 2
500 = EV6
600 = OPEN
700 = OPEN
800 = OPEN
900 = OPEN

Product Description

3, 4 = USED TO DIFFERENTIATE MODELS BASED UPON DIFFERENT
PROCESSORS WITHIN A PROCESSOR TECHNOLOGY (I.E. CLOCK SPEED,
CACHE SIZE) START AT 00 FOR FIRST MODEL AND INCREMENT BY 05 FOR
EACH ADDITIONAL MODEL.
5 = CPU TYPE
BLANK = PENTIUM
1= PENTIUM PRO
2 = PENTIUM II/SLOT 1
3 = PENTIUM II/SLOT 2
4 = Open/Available for future processors
5 = Open/Available for future processors
6 = ALPHA EV56
7 = ALPHA PCA57
8 = ALPHA EV6
