Figure 3 shows the front panel of the Harmony Power System.
Figure 3: Power System Front Panel
The Harmony Power System includes two rows of six RJ-45 ports. The Output Ports are
the top row and the Input Ports are the bottom row.
The ports are numbered 1 through 6. Each Output Port on the top row is paired with
the Input Port that sits below it. For example, port pair 1 corresponds to the left-most
Input Port on the bottom row and the Output Port directly above it.
Note: See “Number of Access Points Supported by the Power System” on page 8
for important information concerning how many APs you can connect to the
Power System.
10/100Base-TX Data Input Ports
The Harmony Power System has six 10Base-T/100Base-TX Input Ports, configured as
MDI (non-crossover Media Dependent Interface). These ports are designed to carry
Ethernet Data over the standard 2 wire pairs (RJ-45 pins 1/2 and 3/6).
10/100Base-TX Data & Power Output Ports
The Harmony Power System has six 10Base-T/100Base-TX Output Ports. These ports
provide both data and power and are configured as MDI (non-crossover Media
Dependent Interface). These ports are designed to carry Ethernet Data over the
standard 2 wire pairs (RJ-45 pins 1/2 and 3/6) as well as DC Power over the spare wire
pair (RJ-45 pins 4/5 and 7/8).
The maximum segment length from a hub or switch to an Access Point, including the
Harmony Power System, is 100 meters (328 feet) using Category 5 twisted pair cable.
