How to fix 'ARP entry addition failed: 5' on Lantronix Server?
The "ARP entry addition failed: 5" message appears because the currently logged-in user lacks the necessary permissions to execute this command on the PC. To resolve this, ask your IT department to log you in with an account that has sufficient rights.
Why 'No Connection With The Device Server' message on Lantronix Server?
The "No Connection With The Device Server" message appears because your computer cannot connect to port 30718 (77FEh) on the device server. Ensure that port 30718 (77FEh) is not blocked by any router on your network and that port 77FEh is not disabled in the device server's security settings.
What to do if Lantronix Server isn't communicating with serial device?
This issue arises when the serial settings for the serial device and the device server do not match. The default serial settings for the device server are RS-232, 9600 baud, 8 character bits, no parity, 1 stop bit, no flow control. Ensure these settings are consistent on both devices.
Why 'No response from device!' error on Lantronix Server?
The error "No response from device! Verify the IP, Hardware Address and Network Class. Please try again." happens because of an incorrect hardware address, an invalid IP address for your logical subnet, or an incorrect subnet mask. Double-check the parameters you've entered. Note that you cannot assign an IP address to a device server through a router.
How to fix Telnet on port 9999 if ping works on Lantronix Server?
This problem can occur due to an IP address conflict on your network, failure to Telnet to port 9999, or the Telnet configuration port (9999) being disabled in the device server's security settings. To resolve this, turn off the device server and run the following commands at the DOS prompt: `ARP -D X.X.X.X` (where X.X.X.X is the IP of the device server) and `PING X.X.X.X`. If you receive a response to the ping, there is a duplicate IP address on the network. If not, use the serial port to verify that Telnet is not disabled.
What to do if Enter doesn't work in Lantronix Server setup mode?
This issue usually arises when you don't press Enter quickly enough after the "Press Enter to go into Setup Mode" message appears. You have only 5 seconds to press Enter before the connection closes. Telnet to port 9999 again, and press Enter as soon as you see the message.
Why Telnet window not responding on Lantronix Server?
This can happen if you entered the Ethernet address incorrectly with the ARP command, the IP address you are trying to assign is not on your logical subnet, or the device server is not properly plugged into the network. First, confirm that the Ethernet address entered with the ARP command is correct, using only numbers 0-9 and letters A-F, separated by dashes (Windows/Unix) or colons (some Unix versions). Next, confirm that your PC has an IP address within the same logical subnet you are trying to assign to the device server. Finally, check that the Link LED is lit, indicating the device server is properly connected to the network.
