Application Notes for CyberPath PowerPath POE4424

Power over Ethernet (PoE) Switch with Avaya IP

Telephones and Avaya Wireless Access Points – Issue 1.1

Abstract

These Application Notes describe the procedures for configuring the CyberPath PowerPath

POE4424 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 POE4424 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.

1. Introduction Power over Ethernet (PoE) allows both power and data to be simultaneously 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 those devices. The IEEE 802.
PAGE 3
The classifications of the phones are dependent on the Institute of Electrical and Electronics Engineers (IEEE) 802.3af classifications for Powered Devices such as Avaya IP Telephones. Each Powered Device is classified by the amount of power that it consumes into one of the IEEE’s five classes. (The IEEE 802.3af PSE and Powered-Device Power Classifications chart can be seen in Table 2).

1. Browse to the IP address configured for the POE4424 and log into the POE4424 using the appropriate administrative privileges. 2. Click Administrator on the left hand pane to open the list of administrative functions available on the POE4424.

3. To configure the POE4424’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 POE4424, Usage Threshold % and Trap Mode, can be configured in the page that gets displayed on the right pane.

6. In the page that appears on the right hand pane, scroll to the desired port number. Select the Power Priority to assign to the port (Low, High, and Critical) and enter the PD Type (optional) for the port, for example, the phone type or other descriptive information. Once finished, click Apply. SCR; Reviewed: SPOC 9/15/2005 Solution & Interoperability Test Lab Application Notes ©2005 Avaya Inc. All Rights Reserved. 8 of 14 CyberPath-PoE.

7. Click PoE Port Status to review the PoE status of all ports on the POE4424. 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

4. Interoperability Compliance Testing The interoperability compliance testing focused on verifying PoE interoperability between the CyberPath PowerPath POE4424 and Avaya IP Telephones and Avaya AP-8 Wireless Access Point. 4.1. General Test Approach The general test approach was to connect the Avaya PDs (Avaya IP Telephones and Avaya AP-8 Wireless Access Point) to PoE-enabled ports on the CyberPath PowerPath POE4424 and verify that the PDs successfully boot.

7. Verify the POE4424 powers up a mix of 23 Avaya IP Telephones. Connect up to 23 Avaya IP Telephones to the POE4424. Connect the 24th port of the POE4424 to an upstream switch. Connect the Avaya Communication Manager, DHCP Server and/or Avaya IP Office to the upstream switch. Power cycle the POE4424 and verify all the Avaya IP Telephones successfully power up and register to their corresponding switch. 6.
