Cisco Access Points - Cabling issues

[jamesg89]

Hi,

I just wondering if there was any documentation that shows what the Maximum cable length can be for Cisco to support their Access Points 

Thanks

100 meters

  E.g. : https://www.cisco.com/c/en/us/products/collateral/wireless/catalyst-9100ax-access-points/deployment-guide-c07-743490.html#:~:text=Note%3A%20The%20Ethernet%20cable%20recommended,328%20feet%20(100%20meters).
 >...The Ethernet cable recommended is CAT-6 with a maximum distance of 328 feet (100 meters). Power required at the Power Source Equipment (PSE) will depend on the cable length and other environmental issues.

thanks for the quick replies both... 

would this be the same for Cisco C9124A?

[Mark Elsen]

Yes!

Thank you, where could i find the documentation that would show that against that particular AP, I've searched everywhere, could do with it as evidence to a discussion I am having.

The standard maximum distance for GigabitEthernet and PoE is 100 meters.

Cable length is a function of the ETHERNET and POE standards not the AP specifications!

Refer to the relevant IEEE 802.3 standards documents for those cable length specifications.

Remember longer cable = greater power loss for POE.
