3.6.1.1.1 a) Ethernet Port 1
The Gigabit Ethernet port 1 (PoE IN and Data) of the device allows the user to connect to the LAN by using Cat5e/Cat6
Ethernet cable, and also power ON the device by using the Power over Ethernet (PoE) Injector supplied with the product
package.

The device receives 48 VDC via a standard Cat5e/Cat6 cable connected between the PoE and the device.

Maximum power supplied to the device is 32 Watts and the device typically draws 12 Watts.
Above 0° Celsius internal temperature, the device need not regulate its temperature, so the power drawn is generally lower in
this temperature range. When the internal temperature gets close to the limits, the device starts to heat itself and the power
draw increases. Powering the device when it is cold, triggers a special self-heat mode where the device is inoperable until the
internal temperature is above -20° Celsius. This is signaled by a solid yellow LED on the Ethernet connector. Once the internal
temperature is above -20° Celsius, the device boots normally.
: Always use a straight cable from PoE to the device. When you use a 4-pair cross over ethernet cable, the reload
functionality gets activated and forcibly deletes the operating image.
3.6.1.1.2 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).
3.6.1.2 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.
Recommended Ethernet Cable Specifications
Type Cat5e/Cat6, STP, 24 AWG, UL rated, UV-shielded and outdoor-rated
Impedance 100 ohms
Cable Length 330 feet / 100 meters
: The total length of cabling between the Personal Computer and the device
cannot exceed 100 meters (includes cable from the Personal Computer to
the PoE, and the cable from the PoE to the device. Due to DC power
requirements, the maximum cable length between the PoE Injector and the
device is 75 meters.
