battery power. For Extreme Networks products, a transition time of less than 20 milliseconds is required 
for optimum performance. 
DC Power Requirements
This system should be installed in a DC-I battery return configuration.In a DC-I configuration, the 
battery return conductor should be connected directly to the central office power return bus, and not to 
the equipment frame or the grounding means of the equipment.
