Assistance Needed – R720 AP LAN2 Port Down When Connecting PC

SandeepKumar — Fri, 18 Jul 2025 14:16:21 GMT

Hi all,
We have connected a PC to LAN2 on the Ruckus R720 access point, but the port is still showing as down. Could someone please confirm whether this port supports a direct PC connection? If it is supported, kindly suggest troubleshooting steps.

Thanks in advance for your support.

Hi Sandeep,

Could you please confirm how the AP is powered?

The AP needs to be powered using a Poe injector or a 802.3 AT for the LAN 2 port to be active.

Refer to Power section on page 6 of below datasheet:

https://webresources.ruckuswireless.com/datasheets/r720/ds-ruckus-r720.pdf

Share the output of below command from AP CLI:

#get power-mode

If the power mode is AF, use the below command to change it to AT.

# set power-mode AT (Make sure the switch port is providing the 802.3AT)
