Power over Ethernet

Power over Ethernet (PoE) technology provides the ability to detect attached Powered Devices (PDs) and deliver 48 VDC to the PD via existing CAT5 cabling. The NetVanta 7100 units are fully compliant with the power delivery options called out in the IEEE 802.3af Power over Ethernet specification. By default, the PoE interfaces discover and provide power to IEEE compliant PDs.

To disable power detection and supply, use the power inline never command in the CLI. To disable power detection and supply from the GUI, select the Ports page. Then select a single port from the list (e.g., eth 0/1). This will bring up the port detail page for eth 0/1. On this page, there is a check box to enable power detection.

Getting Started

Two configuration methods are available for your NetVanta 7100 unit:

  • Web-based GUI
  • AOS Command Line Interface (CLI)

  The GUI lets you configure the main unit settings and provides online guidance and explanations for each setting. However, using the AOS CLI may be necessary for more advanced configurations.

Access the GUI

You can access the web-based GUI from any web browser on your network by following these steps:

Connect the unit to your PC using the first Ethernet port on the front of the unit.

  1. Set your PC to obtain an IP address automatically via Dynamic Host Configuration Protocol (DHCP), or change your PC to a fixed IP address of If you cannot change the PC's IP address, you will need to change the unit's IP address using the CLI. (Refer to the next two sections for instructions.)
  2. Enter the unit's IP address in your browser address line. The default IP address is .
  3. You will then be prompted for the username and password (the default settings are admin and password).
  4. The initial GUI screen appears.


Access the CLI

Access the AOS CLI via the CONSOLE port or a Telnet session. To establish a connection to the NetVanta unit's CONSOLE port, you need the following items:

  • VT100 terminal or PC (with VT100 terminal emulation software)
  • Straight-through serial cable with a DB-9 (male) connector on one end and the appropriate interface for your terminal or PC communication port on the other end

Connect the DB-9 (male) connector of your serial cable to the CONSOLE port on the rear panel of the unit.
  1. Connect the other end of the serial cable to the terminal or PC.
  2. Insert the connector of the provided power cord into the power interface on the rear panel of the unit, and plug the cord into a standard electrical outlet.
  3. Once the unit is powered up, open a VT100 terminal session using the following settings: 9600 baud, 8 data bits, no parity bits, and 1 stop bit. Press <Enter> to activate the AOS CLI.
  4. Enter enable at the > prompt. Enter the enable password when prompted. The default password is password.

The configuration parameters used in the examples outlined in this document are for instructional purposes only. Please replace all underlined entries (example) with your specific parameters to configure your application.


Configure the Unit's IP Address

The following steps create an IP address and subnet mask for the ETH 0/0 interface and add a default route to the route table.

At the # prompt, enter config terminal.
  1. Enter enable password password to assign an Enable Security mode password. This is necessary for Telnet configuration sessions.
  2. Enter interface vlan 1 to access the first Ethernet port on the front panel of the unit.
  3. Enter ip address to assign an IP address to the first Ethernet
    port using a 24-bit subnet mask. Contact your Network Administrator to obtain the IP address (and subnet mask) for your particular configuration.
  4. Enter no shutdown to activate the interface to pass data.
  5. Enter exit to exit the interface commands and return to the Global configuration mode.
  6. Enter ip route to add a default route to the route table. Contact your Network Administrator to obtain the IP address of your default gateway.

Enable Telnet Access

  The following steps create a password of adtran for Telnet access. By default, Telnet access is enabled with a password of password.  

Verify that the prompt of your unit displays (config)#.
  1. Enter line telnet 0 4 to change the configuration parameters for the Telnet sessions.
  2. Enter login to initiate Telnet access.
  3. Enter password adtran to change the login password for the Telnet sessions.
  4. Enter exit to return to the Global Configuration mode.
  5. Verify that the prompt of your unit displays (config)#.
  6. Enter do write memory to save the current configuration.
