Replacement Procedures
This chapter describes the replacement procedures for the Cisco Nexus 7000 Series switch components.
A Cisco Nexus 7000 Series switch is designed for redundancy, which means that you can replace its
modules, fan trays, and power supply units if there is at least one other of the same type operating during
the replacement process.

Replacing an AC Power Supply Unit During Operations
The Cisco Nexus 7000 Series switches use a load-balanced power supply that uses up to three or four
AC or DC power supply units. The AC power supply units convert up to 1.2 kW, 3 kW, 3.5 kW, 6 kW,
or 7.5 kW of AC power to DC power for system operations. The DC power supply units provide either
3 kW or 6 kW of DC power for system operations. If you can set one power supply unit in standby mode
and have the required power load balanced by the remaining online power supply units, you can replace
the standby power supply unit with another power supply unit without interrupting system operations.
