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.
Note
You can have a mix of AC power supplies and HVAC/HVDC power supplies in a chassis.
Before you begin
• The AC or DC power source must be turned off at its circuit breaker.
• The power switch on the power supply must be turned off (power switch set to 0).
• The AC power sources are rated as follows:
Step 1
Open the packaging for the new 3-kW Universal AC/DC power supply and inspect the module for damage.
If the module is damaged, contact the Technical Assistance Center (TAC).
Step 2
For AC input, connect an AC power cable to the AC power source.
Step 3
For DC input, connect a Saf-D-Grid/Saf-D-Grid DC cable to a Saf-D-Grid receptacle, otherwise:
a) Connect the ground terminal ring on the power cable to the ground terminal on the DC power source. Secure it in
place with a nut tightened to the appropriate torque setting for the terminal post.
b) Connect the negative terminal ring on the power cable to the negative (-) terminal on the DC power source. Secure
it in place with a nut tightened to the appropriate torque setting for the terminal post.
c) Connect the positive terminal ring on the power cable to the negative (+) terminal on the DC power source. Secure
it in place with a nut tightened to the appropriate torque setting for the terminal post.
