Chapter 1 Introduction Congratulations on your purchase of the Harmony Power System, a member of Proxim’s Harmony family of wireless networking products. The Harmony Power System provides electrical power to Harmony Access Points over Category 5 Ethernet cabling. The Harmony Power System simplifies the installation and management of the Harmony Access Points on your network: a single cable supplies each Access Point with power and network connectivity.
Introduction 5 The Harmony Family The Harmony Power System is a member of a product family that provides a complete wireless networking solution. • The Harmony Access Point Controller Model 7560 centralizes the management, security, and filtering capabilities of a wireless LAN. The Access Point (AP) Controller communicates with Harmony Access Points over the Ethernet network to provide wireless network access for mobile clients.
Introduction 6 The Product Package Each Harmony Power System comes with the following: • One Harmony Power System • One AC power cord • One rack mounting assembly kit • One CD-ROM containing this user’s guide in Portable Document Format (PDF) • One Harmony Power System Quick Start Guide • One warranty registration card If any of these items are missing or damaged, please contact your reseller or Proxim Technical Support.
Chapter 2 About the Harmony Power System The Harmony Power System is an efficient and simple way to provide operating power to Harmony Access Points. The Harmony Power System supplies DC power to Access Points over the same Ethernet cables that already provide the Access Points with a connection to the network. This chapter contains information about the features of the Harmony Power System and describes the function of its connectors and LEDs.
About the Harmony Power System 8 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.
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.
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.
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.
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.
About the Harmony Power System 13 Description of Front Panel Connectors and LEDs 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.
About the Harmony Power System 14 Channel Status LEDs Each pair of Input and Output ports has one LED indicator that provides information about the channel status. The following table describes the behavior of the six Channel Status LEDs on the front panel of the Harmony Power System.
About the Harmony Power System 15 Description of Rear Panel Figure 4 shows the back panel of the Harmony Power System. Figure 4: Power System Rear Panel Power Socket The switching power supply automatically adjusts its power setting to any supply voltage in the range 100-240 VAC. Serial Port The serial port on the back of the Harmony Power System is nonfunctional and reserved for future use.
Chapter 3 Installing the Harmony Power System Follow these steps to install the Harmony Power System: 1. Choose a Suitable Installation Location. 2. Rack Mount the Harmony Power System (Optional). 3. Power up the Harmony Power System. 4. Confirm That the Harmony Power System Is Operational. 5. Attach the Ethernet Cables. Each of these steps is described in detail in this chapter.
Installing the Harmony Power System 17 Step 2: Rack Mount the Harmony Power System (Optional) The Harmony Power System is 1U (Unit) high and fits in most standard 19-inch equipment racks. Follow the procedure below if you intend to rack mount the unit: WARNING! Disconnect all cables and remove the self-adhesive pads from the underside of the Power System before attempting to rack mount the unit. 1.
Installing the Harmony Power System 18 Step 3: Power Up the Harmony Power System Follow these steps to power up the Harmony Power System: 1. Plug the power cord into the power socket located on the rear panel of the Harmony Power System. 2. Plug the other end of the power cord into an AC power outlet. Once power has been applied, the Harmony Power System will run through its Power On Self Test, which takes approximately 15 seconds to complete. During the self test, the Power LED is amber.
Installing the Harmony Power System 19 Step 4: Confirm That the Harmony Power System Is Operational Monitor the LEDs on the front panel of the Harmony Power System to determine if the unit is functioning properly. When power is applied, the LEDs will turn on and off in the following sequence if the Harmony Power System is working properly: 1. All LEDs turn on for 2 seconds. 2. All LEDs turn off for 2 seconds. 3. The Power LED turns amber while the unit performs the Power On Self Test. 4.
Installing the Harmony Power System 20 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.
Appendix A Safety Information You must read the following safety information before installing or uninstalling the Harmony Power System. Important Safety Information • The Harmony Power System must be installed or uninstalled only by qualified personnel. • The unit should never be connected to an AC outlet (power supply) without an earth (ground) connection. • The unit must be connected to a grounded outlet in order to comply with European safety standards.
• This unit operates under SELV (Safety Extra Low Voltage) conditions according to IEC 950. The conditions are only maintained if the equipment to which it is connected also operates under SELV conditions. WARNING! The RJ-45 ports are shielded RJ-45 data sockets. They cannot be used as telephone sockets. Only connect RJ-45 data connectors to these sockets. Either shielded or unshielded data cables with shielded or unshielded jacks can be connected to these data sockets.

Appendix D 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.
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.
