We have 6 Unifi AP Pro connected on a SG300 52 Port PoE Managed Switch. However, the link on the ports wont go up. We suspect its something in the PoE confiration of these ports. What should be the correct settings and what are the commands to check?
Hello @logbi0791 ,
● Power over Ethernet: Cisco 300 Series Switches are available with up to 48 PoE ports of Fast
Ethernet or Gigabit Ethernet connectivity. This capability simplifies advanced technology deployments
such as IP telephony, wireless, and IP surveillance by allowing you to connect and power network
endpoints over a single Ethernet cable. With no need to install separate power supplies for IP phones
or wireless access points, you can take advantage of advanced communications technologies more
quickly, and at a lower cost. Some models support both IEEE 802.3af PoE and IEEE 802.3at PoE+
while others support IEEE 802.3af PoE only.
Yes, your switch support both versions of PoE.
Thanks in advance.
