Extreme Networks Consolidated Hardware Guide 2-25
Applicable Industry Standards
1 To find VA (Volt-Amps), locate the voltage and amperage requirements for each
piece of equipment. These numbers are usually located on a sticker on the back or
bottom of your equipment. Then multiply the numbers together to get VA:
VA = Volts x Amperes
2 Add the VA from each piece of equipment together to find the total VA requirement.
To determine the minimum amperage requirements for your UPS, we recommend
that you add 30% to the total.
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.
Applicable Industry Standards
