14 p5-570 Technical Overview and Introduction
1.6.2 IBM RS/6000 7014 Model T42 Enterprise Rack
The 2.0-meter (79.3-in) Model T42 is the rack that will address the special requirements of
customers who want a tall enclosure to house the maximum amount of equipment in the
smallest possible floor space. The features that differ in the Model T42 rack from the Model
T00 include the following:
42 EIA units (42U) of usable space
AC power support only
Weight:
– T42 base empty rack: 261 kg (575 lb)
– T42 full rack: 930 kg (2045 lb)
1.6.3 AC Power Distribution Unit and rack content
For rack models T00 and T42 nine-outlet PDUs are available.
PDUs with nine outlets (FC 9176, 9177, 9178, 7176, 7177, and 7178) are available. A T42
rack that is configured for the maximum number of power outlets would have six PDUs (two
mounted horizontally requiring 2U of rack space), for a total of 54 power outlets.
The p5-570 can be connected to any PDU that is available for the 7014-T00 or 7014-T42
racks.
For detailed power cord requirements and power cord feature codes, see the publication Site
and Hardware Planning Information, SA38-0508. An online copy can be found at:

The first four PDUs that are ordered for a rack are mounted vertically in the sides of the rack,
occupying all the four available PDU bays. Any additional PDU will be mounted horizontally in
the rear of the rack and will occupy 1U of rack space.
Universal PDU (FC 7188) and the optional Universal PDU to be mounted horizontally in the
rack (FC 9188) will be available on December 31, 2004, supporting a wide range of country
requirements and electrical power specifications. Each Universal PDU provides 12 C13
power outlets for use within a 7014-T00 or 7014-T42 rack, compared to nine C13 power
outlets provided by the FC 7176 or FC 7177 PDUs. Nine different power cord features can be
used to connect the PDU to a wall power outlet. Each power cord provides the unique design
characteristics for the different power requirements. To match new power requirements and
save previous investments, these power cords could be requested with an initial order of the
rack, or with a later upgrade of the rack features.
1.6.4 Rack-mounting rules for p5-570 and I/O drawers
The primary rules that should be followed when mounting the p5-570 into a rack are:
The p5-570 is designed to be placed at any location in the rack. For rack stability, it is
advisable to start filling a rack from the bottom.
For p5-570 configurations with 2, 3, or 4 drawers, all drawers must be installed together in
the same rack, in a contiguous space of 8U, 12U, or 16U within the rack.
Note: Each p5-570 building block, or a system drawer to be mounted in the rack, requires
two power cords, which are not included in the base system order.
