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

Installing a Power Supply

Wiring a DC Power Connector


Note You can replace a faulty power supply while the system is operating if the other power supply is functioning.


Removing a Power Supply


Caution If you are using a Cisco Nexus 6000 Platform removing the power supply causes the switch to shut down. If you are using two power supplies and you remove one of them, the switch can continue to operate.

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.

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

Installing a Power Supply

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.


Caution In a system with dual power supplies, connect each power supply to a separate power source. In case of a power source failure, the second source will most likely still be available.

Step 6 Verify the power supply operation by checking that the power supply LED is green.

Wiring a DC Power Connector


Warning A readily accessible two-poled disconnect device must be incorporated in the fixed wiring. Statement 1022

Warning This product requires short-circuit (overcurrent) protection, to be provided as part of the building installation. Install only in accordance with national and local wiring regulations. Statement 1045

Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046

Warning Installation of the equipment must comply with local and national electrical codes. Statement 1074

Warning Hazardous voltage or energy may be present on DC power terminals. Always replace cover when terminals are not in service. Be sure uninsulated conductors are not accessible when cover is in place. Statement 1075

Before installing a DC power supply to the switch, you will need to attach DC connection wires that you provide (10 GA recommended) to the DC power connector included in the DC power supply's accessory kit. To wire the connector:


Step 1 Using a 1/8" flat head screwdriver or No. 1 Phillips head screwdriver, loosen the set screws on the connector to freely accept the power wires. The connector will accept 8-24 AWG wires, use what your local electrical code calls for.

Step 2 Strip 1/2" of insulation off the DC wires you will use.

Step 3 Insert the black (DC negative) wire into the right aperture on the connector and tighten down the connection set screw. Finger tight or about 3 ft./lbs should be sufficient.

Step 4 Insert the red (DC positive) wire into the left aperture on the connector and tighten down the connection set screw. Do not tighten over 0.7 Nm.
