FCC ID: R5XXW1
The FCC wants you to know...
This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to Part 15 of the FCC rules. These limits are designed to
provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his
own expense.
CAUTION: Any changes or modifications to this device,
which are not identified in this manual, could cause
harmful interference and void the user’s authority to
operate this device.

This equipment is in the 1st Class category (information equipment to be used in
commercial and/or industrial areas) 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 commercial
and/or industrial areas.
Consequently, when used in a residential area or in an adjacent area thereto, radio
interference may be caused to radio and TV receivers, etc.
Read the instructions for correct handling.
This equipment has been tested for radio frequency emissions and has been verified
to meet VDE 0871 Class A.
Declaration of the Manufacturer to Importer.
We hereby certify that the DIGITAL Server 7100R Series is in compliance with vfg
1046 and is RFI suppressed.
The marketing and sale of the equipment was reported to the German Postal
Service.
The right to retest this equipment to verify compliance with the regulation was given
to the German Postal Service.

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.

The DIGITAL Server provides one or more hot-
swap and redundant 400 W power supplies.
Hot Swap Fans
Automatically turns on redundant fans if a
primary fan failure is detected.
Internal Sensors
Monitors internal server temperatures, fan
operation, voltages, and power supply faults.
Hot Swap Capability
Allows replacement of SBB disk drives, power
supplies, and fans while the server is operating.

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 7100R).
• 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 Description
1-6
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.
