Replacing or Installing Modules, Fan Trays, and Power Supplies
1
Slide and hold the middle handle next to the outer
handle.
2
Fully rotate the release lever away from the front of
the module.
3
Slide the power supply into the open power supply
slot in the chassis until it stops. The front of the
module is about 0.25 inches (0.6 cm) in front of the
chassis.
f) Carefully rotate the ejector lever toward the front of the power supply and be sure that the other end of the lever grabs
the chassis. This pushes the module onto its connectors inside the slot.
The lever will click when you rotate it all the way to the front of the power supply. Be sure that the power supply is
fully inserted into the slot. The front of the power supply will be even with the surface of the chassis.
g) Attach the power cable to the power receptacle on the power supply.
h) Make sure that the other end of the power cable is attached to the power source in one of the following ways:
• If you are using the combined power mode or the n+1 redundancy mode, you can connect the power cable to
the same power source as used by the other power supplies in the same switch.
• If you are using the n+n redundancy mode, you must connect the power cable to the same power source as used
by the other power supplies in the same set of power supply slots in the chassis. The power cables for slots 1
through 4 must be connected to one power source and the power cables inslots 5 through 8 must be connected
to another power source.
i) If you connected the power supply to a DC power source do the following:
1. Turn on the circuit breaker for the DC power source.
2. Turn on the power supply by setting the power switch to on (1).
j) Verify that the OK LED turns on and eventually becomes green.
Installing or Replacing a 3.15-kW Dual Input Universal AC/DC Power Supply
The HVAC/HVDC power supply (N9K-PUV2-3000W-B) has two redundant input power lines. It can provide
power output at 3.15KW with either one or two input power lines operating. The HVAC/HVDC power supply
provides n+n or n+x line redundancy mode in a single power supply for the Cisco Nexus 9500 Series switches.
The HVAC/HVDC power supply accepts 200–240VAC or 240/380VDC input power.
If you are not using power redundancy or are using n+1 power redundancy, you can connect all the power
supplies in the chassis to the same power grid. If you are using n+n power redundancy, connect one set of the
power supply inputs to one power grid and the other set of the power supply inputs to another power grid.
For example, connect grid A to the receptacles closest to the power switch on the power supplies, and connect
grid B to the receptacles furthest from the power switch on the power supplies.
