NOTE
Extreme Networks recommends that you use a UPS that provides online protection.
Calculating Amperage Requirements
To determine the size of UPS that you need, use the following procedure:
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
For more information, see the following ANSI/TIA/EIA standards:
•
ANSI/TIA/EIA-568-A—discusses the six subsystems of a structured cabling system.
•
ANSI/TIA/EIA-569-A—discusses design considerations.
•
ANSI/TIA/EIA-606—discusses cabling system administration.
•
ANSI/TIA/EIA-607—discusses commercial building grounding and bonding requirements.
