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
A DC-powered 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.
The E4G-200 series router can accept -48 or +24 volts for DC input.
Applicable Industry Standards
