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.

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 1000)
Family Name Segment
DIGITAL SERVER 500 SUB ENTRY
DIGITAL SERVER 1000 ENTRY
DIGITAL SERVER 3000 DEPARTMENT
DIGITAL SERVER 5000 APPLICATION
DIGITAL SERVER 7000 ENTERPRISE
DIGITAL SERVER 9000 SUPER ENTERPRISE
• Products in a rackmount chassis will have an R after the Family Name
(DIGITAL Server 3000R).
• 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 part number.

Product Model Numbering Convention
The following example describes the product model numbering convention:
DIGITAL SERVER 1234 5678A 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
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.
