• Category 5 - UTP cable for connecting the system to the existing network
• A PC with an internet browser (IE 5.0 or greater) for configuring the unit
Unpacking and Inspecting the System
Each NetVanta 2000 series unit is shipped in its own cardboard shipping carton. Open each carton carefully and
avoid deep penetration into the carton with sharp objects.

Configuring the System
The NetVanta 2000 series products can be accessed and managed via the LAN interface using an ethernet
crossover cable (provided with the NetVanta 2100). Alternately, the NetVanta 2000 series may be accessed
using a hub and two ethernet cables (one for the PC and one for the NetVanta). Using a PC with an installed
browser (Internet Explorer 5.0 for optimal viewing), the NetVanta can be configured using the web GUI.
2Connecting to the NetVanta
1. Connect the NetVanta 2000 series LAN interface to the PC using the appropriate ethernet cable.
2. Supply power to the PC and the NetVanta unit and begin the operating system boot up process.
During the boot up process, the PC will obtain an IP address from the NetVanta 2000 series DHCP
server. Alternately, complete the process for releasing and renewing captured IP addresses to
obtain a new IP address from the NetVanta 2000 series DHCP server. Please refer to your
specific PC operating system documentation for details on that process.
3. Open your installed browser and in the URL field enter 10.10.10.1. The NetVanta 2000 series login
screen will appear.
4. Enter your username and password and click the login button. When connecting to the NetVanta
2000 series for the first time, the username is admin and there is no set password.
5. After logging in to the NetVanta 2000 series, the welcome screen will appear.
ADTRAN strongly recommends immediately changing the admin password for security
purposes. Refer to DLP-002 in the NetVanta 2000 series System Manual (PN 61200361L1-
1) for details.

Configuring the LAN and WAN IP Parameters
3
The NetVanta 2000 series units come factory programmed with a LAN IP address ot 10.10.10.1 (24-bit subnet
mask) and no pre-programmed WAN IP address. The procedures outlined in this step include changing both the
LAN and WAN IP parameters.
The NetVanta 2000 series supports three types of WAN IP address: Dynamic, Static, and PPPoE (PPP over
Ethernet). The IP parameters for your WAN interface must be supplied by your Internet Service Provider (ISP). If
your ISP is performing DHCP for IP address assignment, configure the NetVanta 2000 series unit for Dynamic
addressing. Use PPP over Ethernet when your ISP has supplied you with the configuration parameters for PPPoE
(including a username and password).
Changing the LAN IP parameters through the LAN interface will result in a loss of management
connectivity. Follow the procedure in Step 2c to change the IP address of the managing PC to
match the new NetVanta LAN IP parameters.
1. Select Config
2. Select Network Interface
3. Enter the Assigned LAN IP address and associated subnet mask
4. Select the Static radio button for static addressing
Your WAN IP address scheme will be supplied by your provider. Static addressing used above
is an example only.
5. Enter the assigned WAN IP address and associated subnet mask
The WAN IP parameters are set by the service provider. Contact your ISP before configuring
the unit.

Changing the IP address to your PC
3b
Alternately, complete the process for releasing and renewing captured IP addresses to obtain a new IP
address from the NetVanta 2000 series DHCP server. The following screen applies to Microsoft Windows 95
to 2000. Please refer to your specific operating system documentation for details on that process.
1. Click Start on the Windows task bar
2. Choose Run, then type WINIPCFG in the text field
3. Click Release to reset all IP parameters
4. Click Renew to obtain new IP parameters
34
3c Configuring the DHCP Server IP Parameters - Optional
The NetVanta 2000 series will automatically populate the DHCP IP address range 1 with ten addresses based on
your assigned LAN network address.
1. Select CONFIG
2. Select DHCP Server
3. Enter an IP address range that is on the same subnet as the assigned LAN IP address of the unit
4. Enter the assigned LAN IP address of the unit

2. Select Yes to configure this as the default
3. Enter all zeros
4. Enter the next hop IP address
This is supplied by your provider

8Select 3DES to invoke Triple DES encryption
9Select SHA to use the Secure Hash authentication Algorithm No. 1
10 Select Pre-SharedKey and enter a 12 character alphanumeric string (spaces are not a valid character)
This key MUST be the same for both the local and remote units.
11 1800 is the ADTRAN suggested value
When determining the appropriate value for your application, typical usage contains a 3:1 ratio
between the IKE and IPSec key lifetime
values. This ratio provides for key negotiation overhead.
