Problems and Error Messages
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.

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 attempted to assign an
IP address to the device server via
the ARP method, “Press Enter to
go into Setup Mode” is displayed.
Now when you Telnet to the
device server, the connection fails.
When you Telnet into 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 will reboot, causing
it to lose the IP address.
Telnet back into 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
message “Press Enter to go into
Setup Mode” 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 message “Press Enter to go
into Setup Mode.”
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.
The IP address you are trying to
assign is not on your logical
subnet.
Confirm that your PC has an IP
address and that it is in the same
logical subnet that you are trying
to assign to the device server.
The device server may not be
plugged into the network
properly.
Make sure that the Link LED is lit.
If the Link LED is not lit, then the
device server is not properly
plugged into the network.
