Hi All,
I am looking to audit the power consumption of my cisco devices. I wanted to know what power my 3750 was consuming so I checked the following data sheet information:
Power Requirements
AC input voltage 100 to 240 VAC (autoranging)
0.6 to 1.2 A, 50 to 60 Hz
DC input voltages for
RPS 2300 and 675
+12 V @13 A
Power consumption 120 W, 409 BTUs per hour
Power rating 0.120 kVA
However, I cannot see where the 120W power consumption comes from as with the supllied AC input voltages I get 288W and when I do the rms calculation to obtain a power rating I get 140kVA!? I'm in a rut here can someone point me in the right direction or at least prove I'm not going mad with my calculations!
Thanks,
Matt.
