Power Over
Ethernet Plus
(PoE+)
You can power the wireless access point with either PoE+ on LAN1 port or
an optional AC/DC power adapter. The wireless access point is a PoE+
Class 4 powered devices, with a maximum power consumption of 25.5
watts. To power the device with PoE+, you have to connect LAN1 port to a
PoE+ source device. The network cable connecting the LAN1 port to the
PoE+ source device carries both network traffic and PoE+.
You can power the device with both PoE+ and an AC/DC power adapter.
However, the two power sources are not load sharing. The power adapter
is the primary power source and PoE+ is redundant power.
Connector Type
The LAN ports have an eight-pin RJ45 connector. The port uses four pins
of the connector at 10/100 Mbps and all eight pins at 1000 Mbps. Refer to
the tables in “Port Pinouts” on page 61 for the pin assignments.
Speed
The LAN ports have speeds of 10/100/1000Mbps. The speeds are set
automatically with Auto-Negotiation. You cannot disable Auto-Negotiation
on the ports.
Note
The LAN ports should be connected to network devices that also
adjusts port speeds with Auto-Negotiation. If a network device does
not support Auto-Negotiation, the LAN ports operate at10 Mbps,
which may reduce network performance.
Duplex Mode
Both LAN ports can operate in either half- or full-duplex mode at
10/100Mbps, and full-duplex mode at 1000Mbps. The ports are IEEE
802.3u-compliant and use Auto-Negotiation to set the duplex mode. You
cannot disable Auto-Negotiation on the port.
Note
The network device to which you connect the LAN ports should also
set the duplex mode with Auto-Negotiation. If a 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.
Automatic MDIX
Detection
The 10/100/1000Mbps twisted-pair ports are IEEE 802.3ab compliant and
feature automatic MDIX detection when operating at 10/100 Mbps.
(Automatic MDIX detection does not apply to 1000 Mbps.) This feature
automatically configures the ports to MDI or MDI-X depending on the
wiring configuration of the port on the Ethernet switch.
You cannot disable automatic MDIX detection. For automatic MDIX
detection to work properly, this feature must also be present on the
Ethernet switch. The LAN port defaults to MDIX if it is connected to a
