Installing or Replacing a Power Supply in a Switch Chassis

You can install up to two power supplies of the following types:
• 3-kW AC power supply (N77-AC-3KW)
• 3-kW DC power supply (N77-DC-3KW)
• 3.5-kW HVAC/HVDC power supply (N77-HV-3.5KW)
If you leave any power supply slots empty, you must install a blank filler plate (N77-3KPS-BLANK-H=) in
that slot to maintain the designed airflow.
You follow the same steps to install AC, DC and HVAC/HVDC power supplies into the switch, but you
ground them differently. For an AC and HVAC/HVDC power supply, you automatically ground it when you
connect its power cable to the power supply and the power source. For a 3-kW DC power supply, you do not
directly connect the power supply to the earth ground.
Hold both handles with both of your hands. Position the alignment pins on the left and right side of the
fan tray to alignment holes in the chassis and press the fan tray into the slot.
