Hi All,

I want to chose the right UPS product for 7 x WS-C3750X-48PF-L in one stack. The Cisco data sheet says 1100W AC, however, I am only connecting 20 IP Phones, each phone will consume around 12.2 Watts.

So in this case, How many watts would I need for the whole 7 switches in the stack ?

in other words, only the first switch in the stack will be connected to 20 IP Phones, but the remaining switches in the stack will be Data Only thought the remaining switches in the stack are capable of delivering a full PoE.

You may also help in letting me know the power consumption of the WS-C3750X-48PF-L with only data connected to it.

Thanks for your help in advance

Ismail
