UPS Transition Time
Transition time is the time that is necessary for the UPS to transfer from utility power to full-load
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.
