Power Outlets
Each model has a specific configuration of standard NEMA outlets, IEC 60320 and IEC 60309 outlets, European
national types (French, Schuko, and UK), or other outlet types (for example, RF-203P-HP 277 VAC). Many
configurations are available or the configurations can be customized to match your needs and your locale.
The outlets are grouped in sets called sections. Outlet sections are preset groups of individual outlets that you
can identify and monitor through the different interfaces that are available with the ePDU.
The outlets are color-coded and labeled. If the model has circuit breakers, the circuit breakers that are
associated with the outlets have corresponding labels (see Figure 5).
