The Cisco Nexus 6000 series support six power supplies, but may be used with three power supplies. You must fill the unused power supply slots with a blank modules to maintain the designed airflow.
If you need to replace an existing power supply, follow the procedures that explain how to remove and install power supplies. If you are installing a new power supply where one did not exist before, follow the installation procedure.
Note The airflow direction must be the same for all power supply and fan modules in the chassis. You can order all modules with front to back airflow but you can alternatively order back to front airflow
This section includes the following topics:
Note You can replace a faulty power supply while the system is operating if the other power supply is functioning.
To remove an AC or DC power supply, follow these steps:
Step 1 Ensure that the system (earth) ground connection has been made. For ground connection instructions, see the “Grounding the Switch” section.
Step 2 Remove the AC power cord or DC wiring connector.
Step 3 Grasp the power supply handle with your left hand.
Step 4 Push against the release latch with your left thumb, and slide the power supply part way out of the chassis.
Step 5 Place your other hand under the power supply to support its weight, and then completely remove the module from the slot.

To install a power supply in a Cisco Nexus 6000 Platform chassis, follow these steps:
Step 1 Ensure that the system (earth) ground connection has been made. For ground connection instructions, see the “Grounding the Switch” section.
Step 2 If the power supply bay has a filler panel, press the latches on the sides of the filler panel, and then slide it out of the power supply bay.
Step 3 Hold the power supply by the handle and position it so that the release latch is on the right, and then slide it into the power supply bay, ensuring that the power supply is fully seated in the bay.
Step 4 Plug the AC power cable or DC wiring connector into the inlet receptacle at the rear of the chassis. For a DC installation, you should secure the plug to the power supply by tightening both captive screws on the plug.
Note Depending on the outlet receptacle on your power distribution unit, you may need the optional jumper power cord to connect the Cisco Nexus 6000 switch to your outlet receptacle. See the “Jumper Power Cord” section.
Step 5 Connect the other end of the power cable to an AC power source. DC sources should connect negative (black wire) and then positive (red wire) connections.
Step 6 Verify the power supply operation by checking that the power supply LED is green.
