Max cable length for POE APs

Max cable length for POE APs

Hello, everybody!

I have about 100 3825i APs, connected to x430-8p switches. Half of the APs works, the other - doesn't. I mean, the amber lights don't blink anyway like there is no signal

I suspect there is something wrong with cable lenght. Do you know any official numbers from Extreme related to the max cable length for POE devices in meters?

Tomorrow I expect a guy with Fluke and we will measure our cables.

Many thanks in advance, Ilya

Hi
As you mentioned it is possible directly by configuring PoE budget in CLI: configure inline-power budget 90

Thank you, Chat!

But how can I apply this "Config option for Standalone Operation" to have 90W? Please, explain.

Many thanks in advance, Ilya

More than 90 meters is not a good idea...

Hello, Andre!

Many thanks for your reply! Could you please let me know what EXOS should I use on X430-8p to make it provide 90W?

Thank you!
