About the Harmony Power System 9
AP Power Over LAN Module
The Harmony OpenAir Access Point must be attached to a Harmony AP Power Over
LAN Module Model 7059 to receive power and data from the Harmony Power System.
Figure 1 illustrates how the AP Power Over LAN Module connects the Harmony OpenAir
Access Point to the Harmony Power System.
The AP Power Over LAN Module receives the combined power and data signal from the
Harmony Power System and then divides this signal into separate power and data
lines through two six-inch cables. The AP Power Over LAN Module includes two
six-inch cables that connect directly to the Harmony Open Air AP’s Ethernet and power
connectors. Refer to the
Harmony AP Power Over LAN Module Installation Guide for
more information.
Note: Each Harmony OpenAir Access Point requires an AP Power Over LAN Module
to connect to the Harmony Power System.
Note to OpenAir Access Point Users
The Harmony Power System will not function properly if connected to multiple OpenAir
Access Points that share the same electrical ground. To avoid this problem, provide
adequate spacing between OpenAir Access Points so that the units do not touch.
Also, you should isolate from ground any OpenAir Access Point whose antennas are
connected to a lightning arrestor or any OpenAir Access Point installed in a
weatherproof enclosure that uses an antenna cable with a grounded bulkhead
connector. Contact your antenna installer for assistance if necessary.
