Replacing or Installing Power Supplies
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 suply 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

Step 1 Ensure that the system (earth) ground connection has been made. For ground connection instructions, see the “Grounding the Switch” section on page
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.
Step 6 If the power supply bay is to remain empty, install a blank power supply filler panel.If you are replacing the power supply, see Installing a Power Supply, page
