The RLXIB-IHA radio accepts 802.3af PoE, with an average power draw of less
than 9 watts. You can also order an optional DC PoE Injector if AC is not
available. The DC power wires must be less than 3 m to meet regulatory
requirements.
The radio shall be installed by trained personnel only, as outlined to the installation instructions
provided with each radio.
The equipment shall be installed by a qualified installer/electrician. The installer/electrician is
responsible for obtaining a secured ground connection between the lug terminal on the surge
protector to a verified common ground point using a minimum 6 AWG gauge wire. This must be
done when attaching power lines to the radio during installation.
A solid ground connection should be verified using a meter prior to applying
power to the radio. Failing to secure a proper ground could result in serious injury
or death as a result of a lightning strike.
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 wires, which are color-coded and cannot be swapped. The
module uses only two of the four pairs.
The Ethernet ports on the module are 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 92) for a diagram of how to configure
Ethernet cable.
