12. Troubleshooting This chapter discusses how you can diagnose and fix errors quickly without having to contact a dealer or Lantronix. It helps to connect a terminal to the serial port while diagnosing an error to view summary messages that may display. When troubleshooting, always ensure that the physical connections (power cable, network cable, and serial cable) are secure. Note: Some unexplained errors might be caused by duplicate IP addresses on the network. Make sure that your unit's IP address is unique. When troubleshooting the following problems, make sure that the XPort is powered up. Confirm that you are using a good network connection. Problems and Error Messages Problem/Message When you issue the ARP -S command in Windows, the "ARP entry addition failed: 5" message displays. When you attempt to assign an IP address to the unit by the ARP method, the "Press Enter to go into Setup Mode" error "(described below) message displays. Now when you Telnet to the device server, the connection fails. When you Telnet to port 9999, the "Press Enter to go into Setup Mode" message displays. However, nothing happens when you press Enter, or your connection is closed. Reason Your currently logged-in user does not have the correct rights to use this command on this PC. When you Telnet to port 1 on the device server, you are only assigning a temporary IP address. When you Telnet into port 9999 and do not press Enter quickly, the device server reboots, causing it to lose the IP address. You did not press Enter quickly enough. You only have 5 seconds to press Enter before the connection is closed. Solution Have someone from your IT department log you in with sufficient rights. Telnet back to Port 1. Wait for it to fail, then Telnet to port 9999 again. Make sure you press Enter quickly. Telnet to port 9999 again, but press Enter as soon as you see the "Press Enter to go into Setup Mode" message.
