Chapter 5 Unix Troubleshooting Tips SMART To add/delete a TCP access list entry, refer to "TCP Access Lists" on page 287. NOTE: When the following procedure is used, the TCP access list will be cleared, but all IP addresses will need to be entered again after the procedure is complete. To reset all TCP/IP values to the factory defaults when access is impossible: 1. Obtain a configuration printout using the control panel. See the 4400 User's Manual for configuration menu information. 2. Power off the printer. 3. On the Ethernet Interface, place SWITCH 1 in the down position. 4. Power on the printer and wait for the ONLINE state. 5. On the Ethernet Interface, place SWITCH 1 in the up position. 6. From a workstation attached to this network segment, create an ARP entry. The Ethernet Interface 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 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. 126
