PoE ports 3,4 WLC 3504 issue

[gustavomam]

Hi,

I am trying to feed an AP3800 from a WLC  3504 on port 3, 4

There is not a valid option via GUI to activate it

I have tried from CLI 

Config port power 3 enable

Result:

An invalid port has been used for this function.

Config port power 4 enable

Result:

An invalid port has been used for this function.

I have confirm with show port summary and  both ID match with port 3 and 4.

WLC is running 8.5.161 which is the latest software supported for client APs.

Do you know if there is any issue on this version related with PoE?

Thank you.

 - AP's can not be directly connected to a controller and should receive POE from a switch-connection.

Hi, for sure I am clear is not best practice at all.

But, client insists to test one AP plugged to WLC and we expected it to work as well.

On WLC 3504 datasheet port 3 and 4 are  PoE capable

Thank you.

The WLC have LAG enable 

Is there any possibility that is not compatible LAG with PoE functionality on port 3 and 4? And that's why got this message?

"An invalid port has been used for this function"

Thank you.

Indeed, Port 3 and 4 will support PoE.  But, you lose LAG support on 1 & 2.  Our client has a 4509 that it is plugged into, but we do not have 2 2.5gig input available to use the onboard 2.5gig port.

To test an otherwise quesitonable AP, i will use the onboard PoE port to drive the AP until we can confirm the problem is the AP or not.

what is PSU you using :

WLC 3504 Power Supply

WLC 3054 has a single Power Supply(PWR-115W-AC). It is dual 12V/54VDC output power supply (with sufficient capacity to support two 802.3at PoE out ports and 12VDC capacity for the system.

Follow below guide and see of that help you :

Hi,

Regarding 2504, same PoE limitation should affect 3504 WLC

"PoE is not available if you have LAG enabled only if it's disabled."
