Application Notes for CyberPath PowerPath POE4408

Power over Ethernet Switch with Avaya IP Telephones and

Avaya Wireless Access Points – Issue 1.0

Abstract

These Application Notes describe the procedures for configuring the CyberPath PowerPath

POE4408 switch to provide inline Power over Ethernet (PoE) to Avaya IP Telephones and

Avaya Wireless Access Points. During compliance testing, Avaya IP Telephones and

Wireless Access Points successfully obtained power and transferred data over standard

Ethernet cables from a CyberPath PowerPath POE4408 switch. Information in these

Application Notes has been obtained through compliance testing and additional technical

discussions. Testing was conducted via the DeveloperConnection Program at the Avaya

Solution and Interoperability Test Lab.

Avaya Solution & Interoperability Test Lab Application Notes for CyberPath PowerPath POE4408 Power over Ethernet Switch with Avaya IP Telephones and Avaya Wireless Access Points – Issue 1.0 Abstract These Application Notes describe the procedures for configuring the CyberPath PowerPath POE4408 switch to provide inline Power over Ethernet (PoE) to Avaya IP Telephones and Avaya Wireless Access Points.

1. Introduction Power over Ethernet (PoE) allows both power and data to be carried over standard Ethernet cables. PoE-enabled Ethernet switches can supply power directly to Ethernet devices, thereby simplifying installation and removing the need for separate power supplies for each device. The IEEE 802.
PAGE 3
Powered device classifications are defined by the Institute of Electrical and Electronics Engineers (IEEE) 802.3af. Each Powered Device is classified into one of five classes. (The IEEE 802.3af PSE and Powered-Device Power Classifications chart can be seen in Section 4.2, Table 3). The powering tests included verification of the following after the product was connected to the switch: • Successful boot operation.

1. Browse to the IP address configured for the POE4408 and log into the POE4408 using the appropriate administrative privileges. 2. Click Administrator on the left hand pane to open the list of administrative functions available on the POE4408.

3. To configure the POE4408’s PoE Usage Threshold and/or SNMP PoE Trap, click Switch Settings on the left pane. In the Switch Settings page right pane, click the PoE tab. 4. The power usage for the POE4408, Usage Threshold % and Trap Mode, can be configured in the page that is displayed on the right pane.

5. To configure POE settings at the port level, click PoE Port Controls in the left hand pane. In the PoE Port Controls pages that appears, scroll to a port such as Port 0.3.

6. The current POE settings for Port 0.3 appear. Admin Mode can be used to enable/disable Power over Ethernet for the port. Power Priority can be used to set the port’s power priority (Low, High, or Critical). Ports with a higher power priority can be powered over those with lower power priority in scenarios where maximum power is reached. Power priority testing was not conducted during compliance testing.

7. Click PoE Port Status to review the PoE status of all ports on the POE4408. Alternatively, the following CLI commands can be used to explicitly enable PoE support on one or all ports, configure the PoE priority of one or all ports, as well as allow users to attach a text string to identify the location and type of PD connected to one or all PoE ports. config inlinepower adminmode enable config inlinepower priority config inlinepower type

Enter the command show inlinepower port summary to verify that PoE support is enabled on one or all ports. The output of the command is shown below. (L2SW) >show inlinepower port summary all Port ---0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.

4.2. Test Results With the exception of the 5602SW IP Telephone scenario described in Note 2, all Power over Ethernet test cases completed successfully. The CyberPath PowerPath POE4408 successfully provided inline power to the Avaya PDs. Table 2 below lists the 802.3af class, allocated power, and measured power of the Avaya PDs when connected to the CyberPath PowerPath POE4408. The measured power listed is for an idle phone.
PAGE 12
Note 1: The 4601 and 5601 IP Telephones do not have a speakerphone. Note 2: The 5602SW IP Telephone used in the lab registered as a Class 1 device but should register as Class 2. When the Speaker volume is set to the maximum on the 5602SW, the POE4408 reports a FAULT on the port because the phone draws more power than permitted for its class, and the POE4408 resets the port. CyberPath does not currently provide a method for overriding the port setting. 5.

7. Conclusion These Application Notes describe the steps for configuring the CyberPath PowerPath POE4408 to provide inline Power over Ethernet (PoE) to the Avaya PDs, namely Avaya IP Telephones and a Avaya Wireless Access Point. During compliance testing, the Avaya PDs obtained power and transferred data over standard Ethernet cables from the CyberPath PowerPath POE4408. 8.
