Connect Hvac/Hvdc Power Supply To Power Source - Cisco NCS 5500 Series Hardware Installation Manual

Connect HVAC/HVDC Power Supply to Power Source

h) Connect the other ends of the power cables to the two DC power circuits. Be sure that the positive and negative cables
attached to one side of the power supply are attached to the same DC power source circuit (with the negative cable
attached to a negative terminal and with the positive cable attached to a positive terminal).
Step 3 Power up the power supply as follows:
a) Turn on the power source circuit breaker for both input lines. Verify that the Input 1 (IN1) and Input 2 (IN2) LEDs
light up on the power supply.
b) Turn the power switch on the power supply to ON (labeled 1 on the power supply). The LEDs should flash and then
the OK LED should turn on (green) in addition to the Input LEDs.

Connect HVAC/HVDC Power Supply to Power Source

The HVAC/HVDC power supply (NC55-PWR-3KW-2HV) has 2 redundant input power lines. It can provide
power output at 3.15KW with either 1 or 2 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 NCS 5500 series modular routers.
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 of 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 For AC input, connect an AC power cable to the AC power source.
Step 2
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 and 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 and 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 and secure
it in place with a nut tightened to the appropriate torque setting for the terminal post.
