cat3560: contrary power and btu information in cco

does anybody know which of the following information about power and btu of the catalyst 3560 is correct?

I found some information in the data sheet (, table 5 power specifications):

C3K-PWR-750WAC: Total output btu/hr 2568

One page down there is mentioned a WS-C3560E-48PD-S (with 265W power supply ??) and 915W power consumption and 561 btu/hr "at the switch" (both @ 100% throughput and max poe loads)

In the power calculator I got the following information for a WS-C3560E-48PD-S with 48 x 7W poe:

336W power consumption and 286.86 btu/hr

Furthermore, is there any information about power consumption and btu for Cat4500 and Cat6500 series switches for different load and throughput profiles?

Many thanks,

Hi Reza,

your're right but there I cannot calculate power ressources needed at different data throughput (e.g. 5%, 25%, 50%, 90%) and cpu load.
