Communications Statements

The following statement applies to this product. The statement for other products
intended for use with this product appears in their accompanying documentation.

Federal Communications Commission (FCC) Statement

Note: The 7014 Model S00 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. 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 an authorized dealer or service representative for help.

Properly shielded and grounded cables and connectors must be used in order to
meet FCC emission limits. Proper cables and connectors are available from
authorized dealers. Neither the provider nor the manufacturer are responsible for
any radio or television interference caused by using other than recommended cables
and connectors or by unauthorized changes or modifications to this equipment.
Unauthorized changes or modifications could void the user's authority to operate the
equipment.

This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two 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.

xii 7014 Model S00 Rack Installation and Service Guide

Chapter 1. Reference Information

This chapter contains information about the 7014 Model S00 rack. Included in this
chapter are locations of rack features, power distribution, and rack specifications.

Power Distribution Systems

This section describes power components and how power is distributed in the Model
S00 rack.

Power may be distributed to the devices and drawers in a Model S00 rack by a
power distribution bus (PDB), a power distribution panel (PDP), or up to two circuit
breaker panels.

Chapter 1. Reference Information 1-1

Power Distribution Bus

A Model S00 rack may contain one or two power distribution busses (PDBs). A PDB
contains eight unswitched 200 V to 240 V AC outlets for providing power to all the
devices and drawers in the rack. Each outlet is connected to a separate circuit
breaker for protection against excessive currents.

Uninterruptible Power Source

An uninterruptible power source (UPS) may be installed in a Model S00 rack
containing a power distribution bus. The UPS contains one power plug (in) and one
power outlet (out) for connecting to the PDB.

Uninterruptible Power Source, Rear View

Chapter 1. Reference Information 1-5

Power Distribution Panel

A power distribution panel (PDP) may be installed in a Model S00 rack to distribute

-48 V DC power to the drawers and devices in the rack. The power distribution
panel provides circuit breakers that protect each drawer in the rack from excess
current and function as DC power switches for switching off power to the devices
and drawers before servicing.

Note: The power distribution panel configurations shown in this manual are for

example purposes only. The actual power distribution panel installed in the
rack you are servicing may vary in terms of circuit breaker ratings, circuit
breaker configurations, and connections to the customer's power source.

The PDP contains a connection location on the rear cover for attaching a customer
supplied circuit breaker alarm. This alarm indicates when any circuit breaker is
switched to the off position.

The circuit breaker switch is on when it is in the up position, and the switch is off
when it is in the down position.

1-8 7014 Model S00 Rack Installation and Service Guide

Power Distribution with the Power Distribution Panel

Note: The -48 V DC Model S00 rack must be connected to a -48 V DC supply

source which is electrically isolated from its AC power source. The -48 V DC
power source must also be reliably grounded.

Note: The -48 V DC Model S00 rack may be connected to more than one power

source.

The circuit breakers in a power distribution panel are mounted on two power bus
bars. The bus bars may be connected either to a common or to separate customer

-48 V DC power sources.
Typically, a PDP connected to two customer power sources will contain two matching

banks of circuit breakers. Each bank of circuit breakers is connected to a separate
power source. The -48 V DC power supply in each drawer in the rack is then
connected to one circuit breaker in each bank of the PDP. Thus, if one of the
customer power sources were to fail, the devices in the rack would still receive power
from the other source.

If a PDP is connected to only one customer power source, then the drawers in the
rack will be connected to only one circuit breaker each.

The exact configuration of power distribution in a Model S00 rack with a power
distribution panel depends on the particular configuration of drawers installed in the
rack. The diagrams on the following pages illustrate several general examples of
power distribution for a standalone Model S00 rack containing a CPU enclosure.
When servicing the power distribution system in a -48 V DC Model S00 rack, take
care to determine the exact configuration being used prior to servicing.

Chapter 1. Reference Information 1-9

The following diagram shows power distribution in a typical Model S00 rack
configuration connected to one customer supplied power source. Note how each
power supply on the CPU enclosure is connected to a separate circuit breaker. Note
also how both banks of circuit breakers in the PDP are connected to the same power
source.

1-10 7014 Model S00 Rack Installation and Service Guide

The following diagram shows power distribution in a typical Model S00 rack
configuration connected to two customer supplied power sources. Note also how
each bank of circuit breakers in the PDP is connected to a different power source.
Note how each drawer in the rack is powered by each power source.

Circuit Breaker Panel

Up to two circuit breaker panels may be installed in a Model S00 rack to distribute

-48 V DC power. Each circuit breaker panel provides 8 circuit breakers that protect
each drawer in the rack from excess current and function as DC power switches for
switching off power to the devices and drawers within a rack before servicing. Like
the power distribution panel, each circuit breaker panel may be connected to one or
two customer power sources.

Two standard circuit breaker panels are available with the Model S00 rack. One
circuit breaker panel contains 8 - 15A circuit breakers. The other circuit breaker
panel contains four 20A and four 10A circuit breakers.

The circuit breaker switch is on when it is in the up position, and the switch is off
when it is in the down position.

Power Distribution with the Circuit Breaker Panel

Note: The -48 V DC Model S00 rack must be connected to a -48 V DC supply

source which is electrically isolated from its AC power source. The -48 V DC
power source must also be reliably grounded.

In general, the power distribution and grounding strategies for a -48 V DC Model S00
rack equipped with a circuit breaker panel is similar to a rack equipped with a power
distribution panel. Basically, the circuit breaker panels accept power from up to two
customer power sources and distribute parallel power feeds to each device in the
rack. Device power cables from a 15A circuit breaker panel are typically connected
first to the terminal strips in the circuit breaker panel chassis, and then from the
terminal strips to the devices.

The exact configuration of power distribution in a Model S00 rack with a circuit
breaker panel depends on the particular configuration of drawers installed in the
rack. The diagram below shows a general example of power distribution for a
standalone Model S00 rack containing a CPU enclosure. When servicing the power
distribution system in a -48 V DC Model S00 rack, take care to determine the exact
configuration being used prior to servicing. Refer to the service guide for the system
or devices in your rack for more information.
