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.
