Hello All,
In the L1 adhoc we are trying to find a way to safely power Type 1&2 PDs over 4 pairs.
We have two options:
1) Detect (at PSE side) that a Type 1/2 PD is capable to be 4P powered
2) Detect (at PSE side) that a Type 1/2 PD cannot be 4P powered
Using a new LLDP TLV would be an example of method 1.
We are looking for a way to do this without a software upgrade at the PD.
As such, we need examples of compliant Type 1/2 PDs that would NOT correctly work when 4P powered.
The definition of not working correctly includes:
- not powering up
- not drawing power over 4P
- puff of smoke
- motorboating
- drawing more power than 25.5W
- ...
Real world examples or theoretical constructs are fine.
These will help us to scope the problem and find solutions.
Thank you!
