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.

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.

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.
