The LAN port is used to connect the device to your Local Area Network
(LAN), typically through an Ethernet switch.
The AT-AP500 Access Point supports Power over Ethernet (PoE+) on the
LAN port. The unit is a PoE+ class 4 powered device with a maximum
power consumption of 17.2 watts. When the port is connected to a PoE+
Ethernet switch, the unit receives its power over the network cable that
carries the network traffic. If you use the PoE+ feature, you do not need to
use the AC/DC power adapter that has to be purchased separately.
The LAN port has an eight-pin RJ45 connector. The port uses four pins at
10 or 100 Mbps and all eight pins at 1000 Mbps. The pin assignments are
listed in "LAN Port" on page 35.
The LAN port can operate at 10, 100, or 1000 Mbps. The speed is set
automatically with Auto-Negotiation. You cannot disable Auto-Negotiation
on the port.
Note
The LAN port should be connected to a network device that also
adjusts its speed with Auto-Negotiation. If the network device does
not support Auto-Negotiation, the LAN port operates at 10 Mbps,
which may reduce network performance.
The LAN port can operate in either half- or full-duplex mode at 10 or 100
Mbps, and full-duplex mode at 1000 Mbps. The port is IEEE 802.3u-
compliant and uses Auto-Negotiation to set the duplex mode. (You cannot
disable Auto-Negotiation on the port.)
Note
The LAN port should be connected to a network device that also
sets its duplex mode with Auto-Negotiation. If the network device
does not support Auto-Negotiation, the LAN port operates at half-
duplex mode. This may result in a duplex mode mismatch if the
network device is operating at full-duplex.
The LAN port has a maximum operating distance of 100 meters (328 feet).
The cable requirements for the LAN port are listed in Table 2 on page 16.
