A rack status beacon junction box (FC 4693) should be used to connect multiple servers to
the beacon. This feature provides six input connectors and one output connector for the
rack. To connect the servers or other components to the junction box or the junction box to
the rack, status beacon cables (FC 4691) are necessary. Multiple junction boxes can be
linked together in a series using daisy chain cables (FC 4692).
Weights:
– T00 base empty rack: 244 kg (535 pounds)
– T00 full rack: 816 kg (1795 pounds)
1.6.2 IBM RS/6000 7014 Model T42 Enterprise Rack
The 2.0-meter (79.3-inch) Model T42 is the rack that will address a client requirement for 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 (42 U) of usable space (6 U of additional space)
Model T42 supports AC only
Weights:
– T42 base empty rack: 261 kg (575 pounds)
– T42 full rack: 930 kg (2045 pounds)
1.6.3 AC Power Distribution Unit and rack content
For rack models T00 and T42, 12-outlet PDUs (FC 9188 and FC 7188) are available.
Four PDUs can be mounted vertically in the 7014 racks. See Figure 1-3 for placement of the
four vertically mounted PDUs. In the rear of the rack, two additional PDUs can be installed
horizontally in the T00 and three in the T42 rack. The four vertical mounting locations will be
filled first. Mounting PDUs horizontally consumes 1U per PDU and reduces the space
available for other racked components. When mounting PDUs horizontally, it is recommended
that fillers be used in the EIA units occupied by these PDUs to facilitate proper air-flow and
ventilation in the rack.

The Base/Side Mount Universal PDU (FC 9188) and the optional, additional, Universal PDU
(FC 7188), support a wide range of country requirements and electrical power specifications.
It receives power through a UTG0247 connector. Each PDU requires one PDU to wall power
cord. Nine power cord features are available for different countries and applications by
varying the PDU to Wall Power Cord, which must be ordered separately. 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 can be requested
with an initial order of the rack, or with a later upgrade of the rack features.
Note: Ensure the appropriate power cord feature is configured to support the power being
supplied.
