Data Integrity and Verification
IBM computer systems contain mechanisms designed to reduce the possibility of undetected data corruption
loss. This risk, however, cannot be eliminated. Users who experience unplanned outages, system failures,
power fluctuations or outages, or component failures must verify the accuracy of operations performed and
data saved or transmitted by the system at or near the time of the outage or failure. In addition, users must
establish procedures to ensure that there is independent data verification before relying on such data in
sensitive or critical operations. Users should periodically check the IBM support websites for updated
information and fixes applicable to the system and related software.

AC Rack Information
This section contains information about ac rack components.
AC Power Distribution Bus
There are two types of ac power distribution buses:
Type 6 power distribution buses have six IEC320-C13, 200 V to 240 V ac outlets. An additional two
front outlets have limited access, as shown in the figures on the following pages. The input ac power to
the bus is not switched, so each outlet has a separate circuit breaker to protect against excessive
current (see the schematic on the following pages). The type 6 power distribution bus feature codes are
9171, 9173, 9174, and 6xxx
Type 7 power distribution buses have nine IEC320-C13, 200 V to 240 V ac outlets. The input ac power
the bus is not switched, so each group of three IEC320-C13, 200 V to 240 V ac outlets has a
separate circuit breaker to protect against excessive current (see the schematic on the following pages).
The type 7 power distribution bus feature codes are 9176, 9177, 9178, and 7xxx.
9188/7188 power distribution buses have twelve IEC320-C13, 200 V to 240 V ac outlets. The input ac
power to the bus is not switched, so each group of two IEC320-C13, 200 V to 240 V ac outlets has a
separate circuit breaker to protect against excessive current (See the schematic on the following
pages.).

A
distribution buses (each consuming 1 EIA location) can be mounted horizontally in the bottom rear of a
Model T00 rack, and three additional power distribution buses (each consuming 1 EIA location) can be
mounted horizontally in the bottom rear of a Model T42 rack. The four vertical mounting slots will be filled
first before consuming EIA locations in the rack. Type 6 ac power distribution buses contain eight 200 V to
240 V ac outlets to provide power to the devices and drawers. For type 6, the input ac power to the bus is
not switched, so each outlet has a separate circuit breaker to protect against excessive current.

DC Rack Information
This section contains information about dc rack components.
DC Power Distribution Panel
power distribution panel can be installed on the top of the rack to distribute -48 V dc power to the
drawers and devices in the rack. The dc power distribution panel provides separate circuit breakers to
protect each drawer in the rack from excess current.
The dc power distribution panel configurations shown in this book are for example purposes only. The
actual dc power distribution panel installed in your rack may vary in terms of circuit breaker ratings,
configurations, and connections to the customer’s dc power source.
The power distribution panel contains a connection on the rear of the panel for attaching a
customer-supplied power alarm. This alarm is activated when any circuit breaker is tripped or is switched
the off position.
The circuit breaker is a single pole, single toggle handle unit with stud terminals, UL, CSA and VDE
approved, black with ″on″ and ″off″ markings, and dc with long trip delay. It is on when the handle is up,
and it is off when the handle is down.

DC Rack Configuration
The dc rack must be connected to an external -48 V dc power source. The -48 V dc power source must
electrically isolated from the ac power source. In addition, the -48 V dc source must be grounded.
The dc rack can be connected to one or two -48 V dc power source to provide redundant power backup. If
two power sources are used, one power source is connected to bus bar A and the other to bus bar B.
The circuit breakers in the dc power distribution panel are attached to two dc power bus bars (bus bar A,
and bus bar B). As described above, these bus bars can be connected either to a common power source
separate power sources (redundant power). Typically, a dc power distribution panel contains two
matching banks of circuit breakers. Each bank of circuit breakers is connected to either bus bar A or bus
bar B. The -48 V dc power supply of each drawer is connected to one circuit breaker in each bank of the
-48 V dc power distribution panel. Thus, when one of the -48 V dc power sources fails, the devices in the
rack still receive power from the other source.
The exact configuration of the dc power distribution panel depends on the configuration of drawers and
devices installed in the rack. Illustrations on the following pages show typical examples of power
distribution for a standalone rack containing a CPU drawer and device drawers.
Note: Before you service the dc power distribution panel, use care to first determine the exact power
configuration and distribution.
The following illustration shows a typical dc power distribution panel (external view).

DC Power Distribution and Ground Illustration
The following illustration is for reference only and shows the power distribution in a typical -48 V dc rack
connected to two -48 V dc power sources. Each power supply in the CPU drawer is connected to a
separate circuit breaker in the -48 V dc power distribution panel.

When the drawer power cords are connected to the dc power distribution panel, make sure there is less
than 1 ohm resistance between the drawer frames or the rack frame.
DC Rack Power Cables
The customer provides the power cables from the -48 V dc power source to the dc power distribution
panel. The -48 V dc rack must be connected to a -48 V dc power source that is electrically isolated from
the ac power source. In addition, the -48 V dc power source must be reliably grounded.
The -48 V dc rack may be connected to two separate -48 V dc power sources. When the rack is
connected to two power sources, both power sources must be reliably grounded.
Power cables used in the United States and Canada are listed by Underwriter’s Laboratories (UL) and
certified by the Canadian Standards Association (CSA). These power cables have the following
characteristics:
Power cables and ground cables must be a minimum of 6 AWG stranded copper (or equivalent) for
lengths up to 50 feet from the power source.
All connectors must be the copper crimp type (compression). Connector metal must be compatible with
the cable metal.

Installation Airflow
Rack airflow requirements are a function of the number and type of drawers installed. All rack installations
require careful site and facilities planning designed to address the cumulative drawer heat output and
provide the airflow volume rates necessary to comply with drawer temperature requirements. Refer to the
individual drawer specifications.
Power Requirements
the U.S., each power distribution bus installed in a rack requires a dedicated power line of 200 to 240 V
ac, 30 A.
other countries, input power to each power distribution bus may vary depending upon country
requirements.
