Remote Power Feeding of Harmony Access Points
The Harmony Power System supplies DC power to Harmony Access Points (APs) over
standard Category 5 twisted pair Ethernet cables eliminating the need for AC outlets,
UPS equipment, and AC/DC adapters for the APs. The Power System employs the
unused pins of a twisted pair Ethernet cable (i.e., pins 4/5 and 7/8) to supply power to
an Access Point.
The Harmony Power System is installed between a network hub or switch and the
Harmony APs. The unit builds off of the existing network infrastructure.
The sole function of the Harmony Power System is to provide power to Harmony APs
over the same Ethernet cabling that already provides the Access Point with network
connectivity; the Power System has no impact on the network data exchanged
between the APs and the hub/switch.
The Harmony Power System is designed for use with a 10/100Base-TX Ethernet
network over a TIA/EIA-568 Category 5 cabling plant.
The Harmony 802.11a and 802.11b APs connect directly to the Harmony Power System
using a Category 5 Ethernet cable. The Harmony OpenAir AP requires that a Harmony
AP Power Over LAN Module be installed between the AP and the Power System. See
“AP Power Over LAN Module” on page 9 for more information.
Number of Access Points Supported by the Power System
The Harmony Power System ships with six (6) pairs of network ports; each pair has
one input port and one output port. However, due to the power requirements of the
Harmony 802.11a Access Point, the Power System can support no more than five (5)
Access Points if you connect one or more Harmony 802.11a Access Points to it.
Important! Do not connect more than five (5) Access Points to this Power System if
you are using one or more 802.11a Access Points (even though the Power
System has six (6) pairs of network ports).
Refer to the chart below to determine how many Access Points you can connect to the
Harmony Power System.

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.
Figure 1: Power Over LAN Module
About the Harmony Power System
10
Typical Network Configuration
Figures 1 and 2 illustrate how a Harmony Power System fits into your existing
networking infrastructure. In Figure 1, the Harmony Power System connects to a
Harmony OpenAir Access Point using an AP Power Over LAN Module. In Figure 2, the
Harmony Power System connects to two Harmony 802.11a Access Points and one
Harmony 802.11b Access Point.
In Figure 2, three Ethernet cables connect the network switch to three Input Ports on
the Harmony Power System. Only data travels over these cables.
Another set of Ethernet cables connects three Harmony Access Points to three Output
Ports. These cables provide the Harmony Access Points with a data connection to the
network switch and with DC power from the Power System.
Note:
The Input and Output ports are paired. If you connect a cable from the network hub/switch to an Input Port, you must use the corresponding Output
Port to provide power and data to an Access Point.
For each Input Port on the Harmony Power System that is connected to the network
hub/switch, an Ethernet cable connects a Harmony Access Point to the corresponding
Output Port.
Figure 2: Connecting Access Points to the Harmony Power System
About the Harmony Power System
11
Keep in mind the following considerations when connecting Access Points to the
Power System:
• The maximum UTP (Unshielded Twisted Pair) cable length is 100 meters (328
feet) over Category 5 cable from the main hub or switch to the Access Point.
•
Proxim recommends using a short UTP or STP (Shielded Twisted Pair) cable of 1 to
2 meters (6-7 feet) between the hub/switch and Harmony Power System and a
longer UTP or STP cable of 1 to 90 meters (300 feet) between the Harmony Power
System and the Access Point. The sum of these two cable lengths cannot exceed
100 meters or 328 feet.
About the Harmony Power System
12
Automatic Device Detection
When a device is connected to one of the Harmony Power System’s Output Ports, the
Power System automatically determines if the device is a Harmony Access Point
capable of receiving power over an Ethernet cable.
If the device is a Harmony Access Point, then the Power System will supply DC power
over the Ethernet cable.
If the device is not a Harmony Access Point, then the Power System will recognize that
the device does not support remote power feeding, and the Power System will not
supply DC power. However, this does not prevent Ethernet data from being
exchanged, so the device will still have a connection to the network through the Power
System (assuming that the device has an external power supply).
WARNING! Proxim recommends that you only connect Harmony Access Points or
Harmony AP Power Over LAN Modules to the Harmony Power System’s
Output Ports. Proxim is not responsible for any damage caused by connecting an incompatible device to an Output Port.
Using the Power System and AC Power Simultaneously
A Harmony 802.11a or 802.11b Access Point may be connected to two power sources
simultaneously. If for any reason the primary power source fails, then the Access
Point will automatically switch over to the second or backup power source and
continue to operate normally.
If a Harmony 802.11a/802.11b Access Point is already connected to a power source via
its AC power adapter when attached to the Power System, then the Access Point will
use the power source from the AC adapter. In this case, if power is removed from the
AC adapter, the Access Point will reboot automatically and then obtain power from the
Power System. If the Harmony 802.11a/802.11b Access Point is already attached to
the Power System when the AC adapter is plugged in, then the Access Point will use
the power source from the Power System. If the Power System loses power, the
Access Point will begin taking power from the AC adapter without interruption (i.e., no
reboot is necessary).
Note:
The Harmony OpenAir Access Point cannot be connected to two power
sources simultaneously.
If at any time the Ethernet cable is disconnected from an Access Point, the Power
System will stop providing power to the port without disrupting Ethernet
communications on the network. The Harmony Power System regularly monitors the
channel status so it learns when an Access Point has been disconnected or
reconnected.

Step 5: Attach the Ethernet Cables
The Harmony Power System includes six Input Ports (the bottom row of RJ-45
connectors) and six Output Ports (the top row of RJ-45 connectors).
Note:
The Harmony Power System can support a maximum of five Access Points if
you are using one or more Harmony 802.11a Access Points. See “Number of
Access Points Supported by the Power System” on page 8 for details.
Follow these steps to attach the Ethernet cables to the Input and Output Ports:
1.
Attach one end of a Category 5 twisted pair Ethernet cable to an Input Port on the
Harmony Power System and the other end to a free port on a network hub or
switch.
Note:
2.
If you want to connect Harmony OpenAir Access Points to the Power System,
attach an AP Power Over LAN Module to each OpenAir Access Point before
proceeding to Step #2.
Attach one end of a second Category 5 twisted pair Ethernet cable to the
corresponding Output Port on the Harmony Power System and the other end to
the RJ-45 port on a Harmony 802.11a/802.11b Access Point or to an AP Power
Over LAN Module.
Note:
Use matching pairs of Input and Output Ports. For example, if you use an
Ethernet cable to connect Input Port 2 to a network hub/switch, then use a
second Ethernet cable to connect Output Port 2 to an AP Power Over LAN
Module or a Harmony 802.11a/802.11b Access Point. Output Port 2 is
located directly above Input Port 2.
3.
Once the Ethernet cable has been attached on both ends, confirm that the port’s
Channel Status LED is green. This means that the Ethernet cable is properly
connected on both ends, you are using the correct cable, and the Power System
has successfully detected a Harmony Access Point.
4.
Repeat the above procedure for each Harmony Access Point that you want to add
to the network. See “Number of Access Points Supported by the Power System”

Use two standard straight-through Ethernet cables that include all 8 wires (4 pairs) to
connect the Harmony Power System to a network hub/switch and to an AP Power Over
LAN Module or Harmony 802.11a/802.11b Access Point. Figure 6 illustrates this type
of connection for an 802.11b Access Point.

Troubleshooting
If the Harmony Power System’s LEDs indicate a problem, refer to the following table,
which contains a list of problems and suggested solutions.
Problem
Suggested Solution
The Power LED does not turn on
after the AC power cord has been
connected.
Check that the power cable is firmly
connected to the Harmony Power System
and to the supply outlet. If the connection is
secure and there is still no power, you may
have a faulty power cord.
How many Access Points does the
Power System support?
The Power System can support up to five
Harmony Access Points if you have
connected one or more Harmony 802.11a
Access Points to the unit. If you are using
only Harmony 802.11b or OpenAir Access
Points, then the Power System can support
up to six Access Points. See “Number of
Access Points Supported by the Power
System” on page 8 for details.
I've connected one Ethernet cable
to the network switch and an Input
Port and a second Ethernet cable
to a Harmony 802.11a/802.11b
Access Point and the corresponding Output Port, but the Channel
Status LED does not turn on.
Confirm that all connections are secure and
that the Harmony Power System is powered
up and operational. Also, one of the
Ethernet cables you are using may be
damaged; try using another pair of cables
instead. Finally, confirm that the cables you
are using are Category 5.

Problem
Suggested Solution
I've connected one Ethernet cable
to the network switch and an Input
Port and a second Ethernet cable
to a Harmony OpenAir Access
Point and the corresponding
Output Port, but the Channel
Status LED does not turn on.
Confirm that you have an AP Power Over LAN
Module installed between the OpenAir
Access Point and the Power System. The
Harmony OpenAir Access Point must be
connected to an AP Power Over LAN Module
to receive power from the Power System.
The Harmony OpenAir Access Point
is receiving power from the Power
System but I cannot communicate
with the network.
Confirm that you do not have the Access
Point’s 10Base-T crossover adapter
connected to its Ethernet port. The Ethernet
cable provided with the AP Power Over LAN
Module should be connected directly to the
OpenAir Access Point’s Ethernet port.
The Power LED remains amber at
all times.
Try recycling power to the unit. If the
situation persists, contact Proxim Technical
Support for assistance.
The Power LED is red.
Try recycling power to the unit. If the
situation persists, contact Proxim Technical
Support for assistance.
