High power PoE #42

Open gkasprow opened 3 years ago

gkasprow commented 3 years ago

There are 60 and 85W PoE modules avaialble from Silvertel. They need an 802.3bt class switch but are backward compatible with AT sources

jordens commented 3 years ago

Nice. To me AT compatibility is crucial, I don't see BT switches very often. I'm really looking forward to active temperature, total power management, sharing, and dynamic limiting on Thermostat and especially Thermostat_EEM.

gkasprow commented 3 years ago

the 802.3bt module has 17mm, it's too high for 4HP EEM

gkasprow commented 3 years ago

But, AG5810 would fit. But would require significant board re-design

jordens commented 3 years ago

Isn't the fan mezzanine (incl screw heads etc) too high for 4 HP anyway? Even if it just fits, wouldn't the fan choke on the proximity to the adjacent board?

gkasprow commented 3 years ago

The idea is to use it when a convection cooling or fan tray is not used. In such cases, we could either install a 2HP filler or go for an 8HP panel.
