The AP3965 has two 10/100/1000BaseT RJ45 LAN ports (see AP3965e Front View) that can be attached directly to a 10/100/1000BaseT LAN segment. This segment must conform to the IEEE 802.3 or 802.3u specifications.
The AP3965 appears as an Ethernet node and performs a bridging function by moving packets from the wired LAN to remote workstations on the wireless infrastructure.
