1.1 Introduction to the H7245 Utility Port Conditioner
The UPC is the power conditioner unit for the VAX 9000 family of computer
systems. The UPC is a free standing unit contained in its own cabinet. The
UPC converts a three-phase, Y-connected ac voltage, obtained from the power
utility, to an isolated and regulated dc voltage of 280 V, and also to improve such
power utility parameters as power factor and harmonic distortion. The UPC
provides the VAX 9000 systems with an auxiliary ac source of 208 V ac to supply
the battery backup units (BBUs) in the systems; a single phase outlet is also
available within the UPC for service instrumentation.

Preparing a Site for the UPC
1.1 Introduction to the H7245 Utility Port Conditioner
The UPC can power loads up to a maximum of 20 kW. Reliability features include
100 ms ride-through capability and modular hardware redundancy.
Depending on the system configuration, a VAX 9000 system can use one or two
UPCs. The main dc output of the UPC is routed to the IOA/IOB cabinet of the
VAX 9000 system from where it is distributed to the system dc converters.
There are two different platforms in the VAX 9000 family of systems: the 210
platform and the 400 platform. The platform type forms part of the model
number of the individual VAX 9000 system. Systems with vector processor
capability are also indicated in the model number by the letters VP immediately
following the platform type. Table 1–1 lists the possible VAX 9000 system
configurations and their UPC requirements.

1.1 Introduction to the H7245 Utility Port Conditioner
1.1.1 Floor Space and Environmental Specifications
The UPC requires a minimum of 121.9 cm (48.0 inches) service clearance space
at the front and rear of the cabinet. The UPC connects to the remote VAX 9000
system cabinets via a set of three cables. These cable sets are offered in lengths
of 3.05 m, 6.10 m, 9.15 m, 12.20 m, and 15.24 m, corresponding to 10 ft, 20 ft, 30
ft, 40 ft, and 50 ft respectively. You must not bolt the UPC to any of the other
cabinets; it must stand alone. You can place the UPC at either end of the cabinet
row or you can place it in a separate room. If you do place the UPC in a separate
room then that room must be on the same floor as the VAX 9000 system. Always
follow local electrical codes and regulations.

1.1.2 Physical Specifications

1.2.1 Power Distribution
The UPC converts utility ac input power to dc output power for distribution
through cables to the VAX 9000 system cabinets. The UPC must receive power
through a single dedicated receptacle protected either by a separate four-pole
circuit breaker, or by an isolation switch. Table 1–5 to Table 1–22 give the
recommended values for the circuit breaker. These circuit breakers and isolation
switches must be fitted with lockout protection devices. You must not connect any
other equipment or loads to the UPC supply circuit.
WARNING
The ac supply socket for the UPC must be adjacent to the UPC and must
be easily accessible.

ATTENTION
La prise de courant alternatif alimentant l’UPC devra être contiguë à

1.2.2 Grounding
Grounding requirements for the UPC ac supply are as follows:
1. You must install an insulated grounding conductor as part of the branch
circuit that supplies the UPC or VAX 9000 system. This grounding conductor
needs to be the same size, have the same insulation material, and be the
same thickness as the grounded and ungrounded branch circuit supply
conductors. To clearly identify the insulated grounding conductor in the
branch circuit, the conductor cable must be green, with or without one or
more yellow stripes.
2. You must ground the branch circuit grounding conductor to earth at the
service equipment or, if supplied by a separately derived system, at the
supply transformer or motor-generator set.
3. You must use only attachment-plug receptacles of a grounding type, in the
vicinity of the UPC or VAX 9000 system. You must connect the grounding
conductors serving these receptacles, to earth at the service equipment.

Using shielded cables passing through an input/output bulkhead

•

Installing gaskets in cabinet panels and doors

•

Grounding the system correctly

If you do not adhere to these practices, then you can invalidate VDE or FCC
certification. Digital has its own electromagnetic compatibility (EMC) standards,
that exceed FCC regulations. The UPC is put through extensive EMC testing.
This is done so that the UPC can be used in most computer room environments
without causing interference to other systems.

2.1.3 Safety Precautions
Observe the following standard safety precautions when installing the UPC:
•

Use caution when removing the UPC cabinet from its shipping pallet; you
require at least two people for this operation.

•

Have a qualified electrician verify proper grounding of power receptacles.

•

Remove all watches and jewelry before working on the UPC.

•

Place all circuit breakers in the OFF position before plugging in the power
cable.

•

Ensure that the UPC is correctly grounded.

•

Ensure that all connections to the utility power supply are correct before
powering-up the system.

•

When performing preventive or corrective maintenance use the lockout/tagout
procedure described in Appendix B.

•

A single individual must never work on the UPC alone.

•

Observe all customer safety procedures.

•

Do not otherwise remove any of the safety covers when the UPC is
operational. After you finishing any work on the UPC, remove all test
equipment and tools before applying power to the system.

2.2 Unpacking and Inspection
The UPC is part of the VAX 9000 System and follows the same unpacking and
inspection procedure. Before you unload the UPC from the truck, check the
location of the installation site in the computer room. Also check the access to the
computer room to determine the order in which you must position the cabinets.
Place the cartons in the unpacking area and unpack them in the required order.
This allows you to unpack each cabinet, and roll it into place without obstruction
from the other system cartons.

3.1 Cabling Considerations
The UPC converts utility ac input power to dc output power and auxiliary ac
output power. Cables distribute the output power to the VAX 9000 system
cabinets. Depending on the customer site, you can mount the utility ac input
receptacle either on a wall or on a cable to the power utility source, as opposed to
hardwiring.
The ac input cable is factory connected, but you must connect the three output
cables during installation. The accessories box, part number CK-H7245-XX,
where XX represents the cable length, contains the three output cables and also
the protective bustle for the IOA cabinet external cables. All external cables
