NOTE
Extreme Networks recommends that you use a UPS that provides online protection.
Calculating Volt-Amperage Requirements
To determine the minimum volt-amperage requirements for your UPS:
1
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.
2
Multiply the numbers together to get Volt-Amps (VA):
VA = Volts x Amperes
3
Add together the VA from all the pieces of equipment to find the total VA requirement.
To determine the minimum volt-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.
