Chapter4 Replacing Components Replacing or Installing Power Supplies
Step 1 Ensure that the system (earth) ground connection has been made. For ground connection instructions,
see the “Grounding the Switch” section on page 2-7.
Step 2 If the power supply bay has a filler panel, press the latches on the sides of t he f ill er panel, and th en 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 ri ght, 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 6004 switch to your outlet receptacle. See the
“Jumper Power Cord” section on page C-8.
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.
