To reset all TCP/IP values to the factory defaults when access is impossible: 1. Obtain a printer configuration printout using the operator panel. See the IBM 6400 Line Matrix Printer Setup Guide (S544-5640) for configuration menu information. 2. Power off the printer. 3. On the Ethernet Interface, place SWITCH 2, the center switch, in the down position. 4. Power on the printer and wait for the READY state. 5. On the Ethernet Interface, place SWITCH 2, the center switch, in the up position. 6. From a workstation attached to this network segment, create an ARP entry. The ethernet IP address and hardware or MAC address are needed. At the workstation enter: arp -s ping 7. Try to "ping" this IP address to see if the Ethernet Interface can be seen on your network. If the interface does not respond, verify you are on the same network segment as the printer and that the ARP entry was created. 8. Telnet into the printer Ethernet Interface using the same IP address as above. Log in as root with no password. 9. At the system prompt, enter: store tcpip from default config http on reset NOTE: This will reset all TCP/IP settings to factory default and reset the Ethernet Interface. 10. Power the printer off and then back on. 11. Set the IP address, subnet mask, and default gateway parameters to the desired values. 2-8 OS/2 Configuration
