It is published internally at Aruba.   I cannot share the full document, but if you have a specific component you are interested in chekcing, let me know.  If you need further validation of this setting, please talk to your local Aruba sales team or partner.

Hi, don´t worry I found the way to do it (I guess).

 

P(BTU/hr) = 3.412141633 × P(W)

 

On the 650 datasheet specifies 

 

Power Specifications

• Maximum power consumption: 126 watts
• Power-over-Ethernet total capacity: 78 watts
• Power-over-Ethernet capacity per port: 19.5 watts

 

So I take the max power and substract the total PoE.

 

126watts - 78watts = 48 watts

 

This is valid for a controller that is no using the PoE

If you use a port with PoE you should add 19.5 watts 

 

The we have to calculete the BTU

 

P(BTU/hr) = 3.412141633 x 48 watts = 163.78.27

 


Thanks for the help.
