You should see a message like this one: Pinging <IP address> with 32 bytes of data If the path is working, you see this message: Reply from < IP address >: bytes=32 time=NN ms TTL=xxx If the path is not working, you see this message: Request timed out If the path is not functioning correctly, you could have one of the following problems: Troubleshooting 4-3 User Manual for the NETGEAR PS121 Mini Print Server · Wrong physical connections -- Make sure the Status LED is on. · Wrong network configuration -- Verify that the IP address for your mini print server and your workstation are correct and that the addresses are on the same subnet. Restoring the Default Configuration This section explains how to restore the factory default configuration settings to the PS121. Use the Default Reset button on the rear panel of the mini print server. Use this method for cases when the administration password or IP address is not known. See "Diagnostic/Reset Push Button" on page 2-6 for a description of this button. Checking the Current Status of the Printer You can check the current status of the printer remotely from the Web configuration screen. · · Current status -- on-line, off-line, out of paper Print State -- either Idle or Printing, depending on the state of the printer You can click the Print Test Page button to print the print server status page. See "Printer Port Screen" on page 4-6 for more information. 4-4 Troubleshooting Appendix A Technical Specifications This appendix provides technical specifications for the NETGEAR PS121 Mini Print Server.

IP Addresses and the Internet Because TCP/IP networks are interconnected across the world, every machine on the Internet must have a unique address to make sure that transmitted data reaches the correct destination. Blocks of addresses are assigned to organizations by the Internet Assigned Numbers Authority (IANA). Individual users and small organizations may obtain their addresses either from the IANA or from an Internet service provider (ISP). The address is usually written in dot notation (also called dotted-decimal notation), in which each group of eight bits is written in decimal form, separated by decimal points. For example, the following binary address: 11000011 00100010 00001100 00000111 is normally written as: 195. 34. 12. 7 The latter version is easier to remember and easier to enter into your computer. In addition, the 32 bits of the address are subdivided into two parts. The first part of the address identifies the network, and the second part identifies the host node or station on the network. The dividing point may vary depending on the address range and the application. These address classes have different ways of determining the network and host sections of the address, allowing for different numbers of hosts on a network. Each address type begins with a unique bit pattern, which is used by the TCP/IP software to identify the address class. After the address class has been determined, the software can correctly identify the host section of the address. The follow figure shows the three main address classes, including network and host sections of the address for each address type.
