Grounding Note on DC Power Supply Connections
DC-equipped Infoblox 4000 Seriess provide 2.5 meter DC power cords with three 10AWG wiring connections, labeled 48V/GND/RTN. DC power
operation requires properly grounded DC connections. Each power supply provides a standard grounding nut, labeled with a standard "Ground"
symbol on the power supply. Ensure that your DC connections are properly grounded before connecting power.
Powering On the Infoblox 4000 Series Appliance
The Infoblox 4000 Series appliances ship with two (2) hot-swappable redundant AC power supply modules or two hot-swappable redundant DC
power supply modules. Infoblox recommends using the power cables shipped with the appliance to connect each power supply to separate power
circuits. In the event of a power failure on one circuit, the appliance can then operate on the other.
To power the appliance:
For each power supply, connect a power cable between the power connector on the back of the appliance and a properly grounded and
rated power circuit that meets the provisions of the current edition of the National Electrical Code, or other wiring rules that apply to your
location. Make sure that the outlet is near the appliance and is easily accessible.
DC Power Supply Guidelines (for Optional DC Configurations)
Note: The information in this section is for advisory purposes only. No color coding standards exist for DC power cables. The color coding used
by the external DC power source at your site determines the color coding for the leads on the power cables that attach to the terminal studs on
each DC power supply. Ensure that DC power connections maintain the correct polarity. The cables of your DC power source also may be
labeled with (+) and (-) to indicate polarity.
Most DC power supply deployments use -48V input.
