Connect HVAC/HVDC Power Supply to Power Source

Connect HVAC/HVDC Power Supply to Power Source
The HVAC/HVDC power supply has 2 redundant input power lines. It can provide a power output of 6.3 kW
from each input power line with 2 inputs operating, or provide 4.8 kW output from either input with one input
operating. The HVAC/HVDC power supply provides n+n or n+x line redundancy mode in a single power
supply for the Cisco 8800 Series Routers.
The HVAC/HVDC power supply accepts a maximum of 305VAC or 400VDC 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 on the rear end of each power tray. If you are using n+n power
redundancy, connect one redundant grid to one of the power supply inputs and the other redundant grid to the
other power supply input on the back of the power tray as shown for each power supply.
Before you begin
• Turn off the power source at its circuit breaker.
• Check that the power switch is set to the STANDBY (0) position on the power tray.
• The HVAC or HVDC power sources are rated for 30A maximum input current.
Procedure
Step 1
Choose your power supply (HVAC or HVDC) and use a Saf-D-Grid power cable to connect to the power
supply tray.
Step 2 For HVAC input, connect a Saf-D-Grid AC power cable to the Saf-D-Grid receptacle.
