Assigning an IP Address to the BROADway System

Should you decide to access the BROADway system remotely through a Telnet or web browser interface, you must either use the default BROADway IP address, or use the TL1 and PS CLI to configure a new IP address for the node.

Default BROADway IP Address

All BROADway systems are configured from the factory with a default IP address of 169.254.0.1 and a subnet mask of 255.255.0.0. This default scheme makes it easy for technicians with a standard DHCP client configured to attach to the unit for configuration purposes, however it also means that two BROADway systems should not be connected to the same network unless at least one of their IP addresses is first changed to avoid conflict.

NOTE: Users with PCs configured with static IP addresses will have to either change the IP address of their PC or of the BROADway system to enable IP communications. For more information, see Assigning a Different IP Address on page 3-4.

To manage the BROADway system using its default IP address, ensure that the PC that will be running the web browser GUI interface is directly attached to the BROADway Ethernet port using either a straight-through Ethernet patch cable (in which case it should be plugged into the port marked with an ‘X’) or a cross-over Ethernet cable (in which case it should be plugged into the other Ethernet port). Start the BROADway system and then restart the PC.

Microsoft Windows will default the IP address of a PC to an address in the range 169.254.0.1 to 169.254.255.255 should no DHCP server be available for certifying a DHCP client. This is known as Automatic Private IP Addressing (APIPA) and is intended to make it easy for home network users to construct small LAN’s. For our purposes, the connection between the BROADway and the PC is a small LAN.

The following procedures are to be used for different Windows Operating System versions - note that these procedures will not upset the IT configuration of the PC; when you reboot the PC on the corporate network it will automatically re-acquire a proper IP address from the corporate DHCP server.

Windows 98 and Windows NT: Click the Start button, then Run, then type winipcfg and click OK. From the drop-down list select your network interface card and then click Release, then Renew. The NIC will be assigned a new address in the 169.254.X.X range.

Windows 2000, XP: Reboot the PC and wait approximately 60 seconds for the DHCP client to timeout - the DHCP client will then default the IP address to the correct range.

To verify that the PC has an IP address in the correct range click the Start button, then Run, then type command and click OK. At the prompt, type IPCONFIG and press ENTER. The IP address of your LAN interface should begin with 169.254.X.X and the subnet mask should be 255.255.0.0. Type exit to exit the command shell. You can verify connectivity with the BROADway system by using the PING 169.254.0.1 command from the Windows command shell prompt.

You are now ready to configure the BROADway system through the GUI as described in Logging In With the Web Browser Interface (GUI) on page 3-9,or by using a Telnet program as described on Ethernet Port Command Line Access on page 3-8.
