I am needing to buy some UPS devices for my development network.
I read the following from a Cisco web site and was wondering if this is accurate?
"The 3750 is given in terms of voltage and current (amps), so now just multiply the two to obtain VA. Just for the fun of it, sometimes the load is given in watts, if so, as a rule of thumb, divide given wattage figure by 0.7 to obtain For example, the 3750-48TS is close to 75 watts, therefore: 75/.7=107 volt-amps."
"VA are commutative so now just add up each of your VAs. Toss in around 30% fudge factor so you can add more switches. You need to support 60 minutes for 214 (total VA for both 3750's) + 64 (30% fudge factor) and your grand total is 278 VAs."
"Add there ya go! I would make sure the whatever UPS I used would do power conditioning and monitoring so I know when the battery is getting...
