Chapter 1. General description 31

1.12.7 The AC power distribution unit and rack content

For rack models T00 and T42, 12-outlet PDUs are available. These include PDUs Universal

UTG0247 Connector (#9188 and #7188) and Intelligent PDU+ Universal UTG0247

Connector (#7109).

Four PDUs can be mounted vertically in the back of the T00 and T42 racks. Figure 1-6 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 will be filled first in the T00 and T42 racks. Mounting PDUs horizontally

consumes 1U per PDU and reduces the space available for other racked components. When

mounting PDUs horizontally, use fillers in the EIA units occupied by these PDUs to facilitate

proper air flow and ventilation in the rack.
