Enterasys C5K125-48P2 Not Passing the correct amount of power of PoE+

Jose_Figueroa — Thu, 07 May 2015 07:04:00 GMT

I've been running into a lot of problems with poe devices that are class4 and require PoE+. I have VoIP phones that aren't getting the correct amount of power. I have lldp enabled on the port with the phone.

Is there any known issues with PoE+ that anyone has seen?

I fixed our phone issue by telling the phones (cisco) to not use power negotiation, but its not working its expansion module.

Just wanted to check and see if there were any updates to the issue so that this can be marked "solved."

We have released firmware version 6.81.06.0002 on the C5/B5 to support the negotiation of PoE via LLDP.
