Application Notes for Dell PowerConnect™ 3448P Power over Ethernet (PoE) Switch with Avaya IP Telephones – Issue 1.0

Abstract

These Application Notes describe the configuration of the Dell PowerConnect™ 3448P switch to provide inline Power over Ethernet (PoE) to Avaya IP Telephones and Avaya Wireless Access Points. Avaya IP Telephones and Wireless Access Points successfully obtained power

and transferred data over standard Ethernet cables from a Dell PowerConnect™ 3448P layer 2 switch.

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. In the configuration described in these Application Notes, a Dell PowerConnect™ 3448P switch is configured to supply inline PoE to Avaya Powered Devices (PDs), specifically Avaya IP Telephones and Avaya Wireless Access Points.

The Dell PowerConnect™ 3448P allows the prioritization of power to ports. There are three levels of priority that can be assigned. The default priority is labeled “Low”. The highest priority is labeled “Critical” and the middle priority is labeled “High”.

As illustrated in Figure 1, the Avaya IP endpoints covered in these Application Notes include the following:

• 4601 IP Telephone

• 4602 IP Telephone

• 4602SW IP Telephones

• 4610SW IP Telephone

• 4620 IP Telephone

• 4620SW IP Telephone

• 4621SW IP Telephone

• 4622SW IP Telephone

• 4625SW IP Telephone

• 4630SW IP Telephone

• 5601 IP Telephone

• 5602SW IP Telephone

• 5610SW IP Telephone

• 5620SW IP Telephone

• Avaya Gen-2 4606, 4612, and 4624 IP Telephones

• Avaya AP-8 Wireless Access Point

The Avaya 4612 and 4624 IP Telephones can be identified as Gen-2 by inspecting the model number. “2A” in the model number indicates Gen-2. The model number can be found by:

• Inspecting the label attached to the bottom of the Telephone. OR

• Pressing Mute, V, I, E, W, # on the keypad and then pressing

appears. Press # to exit.

An example of a model number is 4606D02A-003 (Gen-2).

The power tests included verification of the following after the product was connected to the switch:

• Successful boot operation.

• For Avaya IP Telephones, successful registration with Avaya Communication Manager

or Avaya IP Office (the Avaya 5600-Series IP Telephones are only supported on IP Office), completion of a test call, and raising speakerphone volume to maximum value.

• Connecting a mix of Avaya IP Telephones and a Wireless Access Point to the switch,

power cycling the switch and verifying successful boot operation and registration of the devices to IP Office and Avaya Communication Manager.

3. Configure Dell PowerConnect 3448P

This section describes the switch VLAN configuration.

Power over Ethernet (PoE) support is available on all ports of the Dell PowerConnect™ 3448P. The port settings are configured by default to Auto. This enables the Device Discovery protocol to automatically detect when a device is connected that needs power. All Avaya telephones that are in this document automatically get power when connected to the defaulted ports. The Dell

PowerConnect™ 3448P switch supports a maximum of 370 Watts. This limits the number of 4620/5620 IP sets that can be simultaneously supported to 46. There was no PoE specific configuration done for this test.

3.1. Getting Started with a New or Initialized System

1. Identify the IP Address, Subnet Mask and Default Gateway that will be used for the Dell

PowerConnect™ 3448P switch.

2. Connect to the Dell PowerConnect™ 3448P Switch with its serial cable. Run a terminal

emulator, such as HyperTerminal with settings of 9600Kb/s, 8 data bits, 1 stop bit and no parity. Set the flow control to none and change the emulation mode to VT100.

3. Power on the Dell PowerConnect™ 3448P switch. The following Wizard is displayed in

the HyperTerminal Window when the Dell PowerConnect™ 3448P switch is turned on with all of the factory defaults.

Welcome to the Dell Easy Setup Wizard The Setup Wizard guides you through the initial switch configuration and gets you up and running easily and quickly. You can also skip the setup wizard, and enter CLI mode to manually configure the switch if you prefer. You can exit the setup wizard any time by entering [CNTRL+Z]. The system will prompt you with a default answer. By pressing Enter, you accept the default value.

Would you like to skip the setup wizard? [Y/N] N

4. Select N and then press Enter.

5. The following SNMP screen is presented. Choose to skip this step (Backspace over the

Y and type N and then press Enter).

The system is not setup for SNMP management by default. To manage the switch using SNMP (required for Dell Network Manager) you can:

• Setup the initial SNMP version 2 account now.

• Return later and setup the SNMP version account. (For more

information in setting up a SNMP version 2 account, see the user documentation). Would you like to setup the SNMP management interface now? [Y/N]Y

6. Configure the accounts and password for the switch.

Now we need to setup your initial privilege (Level 15) user account. This account is used to login to the CLI and Web interface. You may setup other accounts and change privilege levels later. For more information on setting up user accounts and changing privilege levels, see the user documentation. To setup a user account: Please enter the user name: admin Please enter the user password: ***** Please reenter the user password: *****

7. Configure the IP Address and Subnet Mask of the Dell PowerConnect™ 3448P.

Next, an IP Address is setup. This IP Address is defined on the default VLAN (VLAN #1), of which all ports are members. This is the IP Address that you use to access the CLI, Web interface or SNMP interface for the switch.

To setup an IP address:

Please enter the IP address of the device (A.B.C.D): 172.16.254.99

Please enter the IP subnet mask (A.B.C.D or /nn): 255.255.255.0

8. Configure the Gateway.

Finally, setup the default gateway. Please enter the IP address of the gateway from which the network is reachable (e.g. 192.168.1.1): 172.16.254.4

This is the configuration information that has been collected: SNMP Interface=”Dell Network Manager”@192.168.1.10 User Account setup = admin Password = ***** Management IP Address = 172.16.254.99 255.255.255.0 Default Gateway = 172.16.254.4 If the information is correct, please select [Y] to save the

configuration, and copy to the start-up configuration file. If the information is incorrect, select [N] to discard configuration and restart the wizard: [Y/N]: Y
