XPort™ User Guide 54

8: 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 be displayed. 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 Reason Solution

When you issue the ARP –S

command in Windows, The

ARP entry addition failed: 5

message displays.

Your currently logged-in user

does not have the correct rights

to use this command on this PC.

Have someone from your IT

department log you in with

sufficient rights.

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 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.

Telnet back to Port 1. Wait for it to

fail, then Telnet to port 9999

again. Make sure you press Enter

quickly.

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.

You did not press Enter quickly

enough. You only have 5

seconds to press Enter before

the connection is closed.

Telnet to port 9999 again, but

press Enter as soon as you see

the Press Enter to go into Setup

Mode message.

When you Telnet to port 1 to

assign an IP address to the

device server, the Telnet

window does not respond for a

long time.

You may have entered the

Ethernet address incorrectly with

the ARP command.

Confirm that the Ethernet address

that you entered with the ARP

command is correct. The Ethernet

address may only include

numbers 0-9 and letters A-F. In

Windows and usually in Unix, the

segments of the Ethernet address

are separated by dashes. In some

forms of Unix, the Ethernet

address is segmented with

colons.
