Four PDUs can be mounted vertically in the back of the T00 and T42 racks. Figure A-2 shows
the placement of the four vertically mounted PDUs. In the rear of the rack, two additional
PDUs can be installed horizontally in the T00 rack and three in the T42 rack. The four vertical
mounting locations are filled first in the T00 and T42 racks. Mounting PDUs horizontally
consumes 1U per PDU and reduces the space that is available for other racked components.
When mounting PDUs horizontally, the preferred approach is to use fillers in the EIA units that
are occupied by these PDUs to facilitate the correct airflow and ventilation in the rack.

The PDU receives power through a UTG0247 power-line connector. Each PDU requires one
PDU-to-wall power cord. Various power cord features are available for various 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 specific 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.
