isolation, but it does not
isolate two simultaneously connected external supplies from one another.
The external Power Connector also provides connections for an optional battery backup
enclosure or for power sources such as solar panels, etc.
LED Indicator
An optional LED indicator is available and plugged into the Console port when available.
Earth Connections
There are several points within the RX INN that should be grounded. For correct operation
and protection each of the individual antenna lighting suppressors should be grounded during
the installation of the equipment. The back of the RX INN has several mounting points that
should be used for earthing.
If the RX INN is powered by the Ethernet port then either shielded external grade Ethernet
cable should be used or a PoE Lighting Suppressor that supports grounding should be
installed. The preferred method should be determined by the installation on a per site basis.
The use of shielded RJ45 jacks along with a metal housing helps reduce the effects of EMI
interference. Additional features include a ground lug and terminal provided directly on the
lightning protector housing allowing for superior grounding.
For maximum protection from lightning on long cable runs, two units can be used, one at each
end of the cable. A PoE injector, similar to that shown below, is supplied as a standard item
with each RX INN.
Battery Backup Options
A high availability battery backup solution is available for the RX INN which is ordered
optionally and can be field installable.
The RX INN battery backup option (RX-UPS50) is a multipurpose power supply providing
primary and standby power to RX Intelligent Network Nodes (INN). The multipurpose power
supply provides filtered and regulated 50W output power during normal line operation. During
line disruptions, the RX-UPS50 supplies uninterrupted regulated output power of 50W, using
a string of four 7.2Ah batteries.
