Mixed combinations of the 6.0kW and 7.5kW power supplies is supported. The power redundancy
modes are designed to determine the optimum power for the combination of power supplies
installed, helping ensure system availability.
The 6.0kW power supply supports operation with 110 and 220V inputs on either or both of the two
inputs, which results in different levels of output power for the different redundancy modes.
Table 5 shows the maximum system output power that can be drawn from three 6kW power
supplies in a chassis with different combinations of input voltage and redundancy modes.

Features and Benefits
Table 7 summarizes the features and benefits of the Cisco Nexus 7000 Series Power Supply
Modules.

Features and Benefits
Feature
Benefit
Multiple inputs
Provide redundancy within the power supply unit; if one input fails, power is still drawn from
the other input
the other input
Universal input (110 to 240
VAC and 50 to 60 hertz [Hz])
(6000W only)
VAC and 50 to 60 hertz [Hz])
(6000W only)
●
Flexibility to provision circuits with either high-input voltage (200 to 240V) or low-input
voltage (100 to 120V), depending on availability and power output needs
●
Capability to connect one input with a 220V line and the other with a 110V line
