CISCO ISR 4351 and ISR 4451-X Heat Dissipation

[Stevendavis777]

Hello Community,

I am in need of the heat dissipation values for the CISCO ISR 4351 and ISR 4451-X models and cannot seem to find them. Preferably in BTU/hr as I am designing a HVAC system.

Any help is greatly appreciated

Unsure how exact or applicable this is, but came across mention that about 3.4 watts equals 1 BTU.

While trying to determine actual heat generation, perhaps the foregoing will provide a rough estimate.

Sound good thank you!,

Does anyone know the efficiency numbers for these machines?
