Dear Reddit r/networking community,
first post, hooray! If I break any rules or am not conforming to the netiquette of this community please accept my apologies.
TL;DR Do you know a (24/16/8 port) switch with 802.3bt power envelope for each individual port?
This is question comes after a brainstorming session regarding setting up bold remote (rural) computer classrooms. Because Rural schools have limited access to IT technology and electrical energy.
To tackle the challenge of IT technology a modular low power computer system with custom OS was created by volunteers.
Some information regarding our project can be found by googling" educaid KUBO toolkit".
Since setting up these systems in our 2 pilots we have noticed the frustration of the second limitation being affordable and reliable access to energy.
The idea now is to use a PoE switch that can deliver next to data also energy to the low power computer systems. How this switch is going to be powered is another question with another technical background not to be discussed here.
Because the combination of a monitor and the low power computer system consumes an easy 30Watt the 802.3af and 802.3at standards do not make the cut.
802.3bt with its 51W to 60W power envelope will suffice for our project needs (computer systems, monitor, lights, fans,…)
Upon researching the necessary primary building block, being a 802.3bt switch the plethora of vendors and models were reviewed. And here it is where we could use your expertise. From research there are no 24/16/8 port switches that provide the 51-60W power envelope to each port.
Some examples:
Vendor A has a 24 port switch with only 8 ports 802.3bt enabled and the rest is 802.3af.
Vendor B has a 16 port switch which are all 802.3bt but has a total capacity of 300Watt (300 / 16 = 19 Watt per port, not enough)
Because there are so many models and so many vendors, I am wondering if the community knows of a model or a vendor that has a 24/16/8 (we aren’t fussy) port switch which has 802.3bt (50Watt) available power for each port?
Thank you very much
