User Manual
Using Power over Ethernet (PoE) to power remote devices has several
advantages including:

"Carrier Class" Power Over Ethernet System.

Power can be supplied over long distances, up to 300 feet.

Power can be available wherever network access is available.

The power supply can be centrally located where it can be attached to an
uninterruptible power supply.

The user has the ability to easily power on reset the attached equipment from
a remote location.

There is no need to run additional power cabling to the device as power can
be supplied over the CAT5 Ethernet cable.

Used for remote mounted radios to save on cost of coax and reduce RF
losses.

Built-in Ethernet Surge protection to prevent equipment damage.

Overload and Short Circuit protection.
6.2.2 Ethernet Cable Specifications
The recommended cable is Category 5 or better. A Category 5 cable has four
twisted pairs of wire, which are color-coded and cannot be swapped. The module
uses only two of the four pairs.
The Ethernet port on the module is Auto-Sensing. You can use either a standard
Ethernet straight-through cable or a crossover cable when connecting the
module to an Ethernet hub, a 10/100 Base-T Ethernet switch, or directly to a PC.
The module will detect the cable type and use the appropriate pins to send and
receive Ethernet signals.
Ethernet cabling is like U.S. telephone cables, except that it has eight
conductors. Some hubs have one input that can accept either a straight-through
or crossover cable, depending on a switch position. In this case, you must ensure
that the switch position and cable type agree.
Refer to Ethernet cable configuration (page 84) for a diagram of how to configure
Ethernet cable.
