We're looking into the possibility of setting up a pilot VOIP project. I need help with the following -- need some btu figures.
I'm looking at using the Cisco 3650 POE 24 port switch, I'll need two for a total of 48 ports.
1. How large of an APC (battery backup) do I need to keep the phones up for 24 hours -- please list makes and models if possible?
2. How much heat in BTUs does the battery backup (selected in option #1) and switch selection generate?
Any other calculations and or numbers I'll need to determine my cooling requirements?
