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 Since Unix environments rely on TCP/IP to communicate with the Ethernet Interface, crossing routers becomes an issue. After following one of the Ethernet Interface configuration methods mentioned (other than the BOOTP method), you will most likely 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. In order to communicate across a router, it is best to 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 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. Load a Web browser on your Unix 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. 2. At the "Network Configuration" HTML form that displays, click in the first field below the "Gateway" heading and type in the IP address of the default router/gateway for the Ethernet Interface subnet. 3. Click on the SUBMIT button when done. Host Configuration There may be times when you would prefer to or have to perform the manual setup steps for a new printer definition. There may also be times when you require a less common print solution such as direct socket capabilities. This section covers these additional setups. 5-8 Unix Confuiguration
