LAN Port
The AT-TQ5403e access point has one LAN port to connect to your Local
Area Network (LAN), typically through an Ethernet switch.
Power over
Ethernet (PoE)
The AT-TQ5403e access point supports Power over Ethernet Plus (PoE+)
on the LAN port. The access point is a PoE+ class 4 powered device with
a maximum power consumption of 25.5 watts. When the port is connected
to a PoE+ Ethernet switch, the access point receives its power over the
network cable that carries the network traffic. The LAN port is the only way
to supply the power to the device.
Note
The PoE device that supplies power to this device, such as a switch,
must be a UL listed Information Technology Equipment (ITE).
Connector Type 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 49.
Speed 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.
Duplex Mode 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.
