Enclosure Power Loads
enclosures installed. For examples of calculating the power and current load for
various enclosure combinations, refer to Calculating Specifications for Enclosure
Combinations on page 3-11.
In normal operation, the AC power is split equally between the two PDUs in the
modular cabinet. However, if one of the two AC power feeds fails, the remaining AC
power feed and PDU must carry the power for all enclosures in that cabinet.
Power and current specifications for each type of enclosure are:

Half of the plugs for an enclosure must be connected to the right-side PDU and the other half connected to the
left-side PDU. PDUs must be supplied from separate branch circuits.

Maintenance switch has only one plug. This plug must be connected to the right-side PDU (the PDU that is
supplied by a UPS, if installed).

Total apparent power is the sum of the two AC power lines feeding the enclosure. Electrical load is shared
equally between the two lines.
