3.1.1.1.2 b) Ethernet Port 2
The Gigabit Ethernet Port 2 is used for PoE OUT and data.
While using this port, the following points should be considered:
48 VDC (15 W average) is present on the second Ethernet port. Make sure the connected device can support this
voltage.
If power from the second Ethernet Port is desired, then Proxim recommends you to use 60W PoE (not supplied).
If a device is connected to the second Ethernet port for data only, then use a PoE Splitter (not supplied).
3.1.1.2 Serial Port
The Serial Port is used for debugging and management, and Audible Antenna Alignment through Command Line Interface
(CLI).
The serial connection is established with an RJ11 to DB9 connector (also referred to as a "dongle") by connecting the RJ1 end
of the dongle connector to the device and the other end to your Personal Computer.
The pin assignments for DB9 connector are as follows:
: The pin6 on RJ11 connector is used as input for 12V DC IN for diagnostic purpose. Supplying power on this pin, when
the device is powered by POE injector, might damage the device.
