Hi All

I have a query


IN s5720 / s2700 switch i need to upgrade the inline power for end device .



1) What is the maximum voltage (POE+) / per port , that S5720 & S2700 can support

2) what is the configuration required to change the settings from POE to POE +, port wise

3) default voltage per port , of both the switch .


Regards

hi, I checked, S5320 supports 802.3af(15.4w) and 802.3at(30w), and the the it's same for the S2700.
I think you can check if the PoE consumption has reached the maximum power that the s2700 could supply.
A device provides power for PDs in conformance to 802.3at(poe+) by default. if you changed it to poe, you could use command undo poe af-inrush enable to resotre the default setting.

POE TO  POE+ with maximum Volatage  rating-2977711-1

POE TO  POE+ with maximum Volatage  rating-2977711-2
2. By default, the switch interfaces comply with 802.3at(PoE+).
The poe af-inrush enable command changes the power supply standards of interfaces from 802.3at to 802.3af(PoE).
The poe { at-inrush | pre-bt-inrush | bt-inrush } enable command changes the power supply mode of interfaces supporting the 802.bt(PoE++) mode.

3. The default voltage is 48V DC.
