Communicating Across Routers 2. Turn the Ethernet Interface on so that it immediately sends out a BOOTP request. Wait one minute to allow the IP address assignment process to complete. You should see the STAT LED (on the Ethernet Interface) slow down, indicating it knows about an IP address to use. 3. Try to ping the Ethernet Interface IP address from a network station to see if it can be seen on your network. NOTE: You will be able to communicate with the Ethernet Interface from network stations on different subnets if the print server has been told about its default router/gateway in the BOOTP response from the BOOTP server. Communicating Across Routers SMART Since Unix environments rely on TCP/IP to communicate with the Ethernet Interface, crossing routers becomes an issue. After you have followed one of the Ethernet Interface configuration methods mentioned (other than the BOOTP method), most likely, you will only be able to communicate with the print server from the same subnet. This means any host across a router will not be able to see your Ethernet Interface. To communicate across a router, store a default router/gateway within the print server so that any packets destined for another subnet get forwarded to this router automatically. The router (or series of routers) can then take over the process of ensuring the packets get to their final destination on another subnet on your network. To configure a default router/gateway within the Ethernet Interface: 1. Start a Web browser on your local station and direct it to the URL: http://EthernetInterfaceIPaddress/ networkConf.html (e.g., http://192.75.11.9/networkConf.html). NOTE: If prompted for a "User ID" and password first, type in root for the ID and press ENTER at the password prompt (since there is no default password). 115
