Problem/Message
Reason
Solution
When you attempt to assign an
IP address to the unit by the
ARP method and Telnet to the
device server through port 1, the
connection fails.
The ARP method only creates a
temporary password. When you
Telnet to port 1, the connection
should fail. 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
within 5 seconds.
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.
To enter Setup Mode via Telnet,
the Enter key must be pressed
within 5 seconds.
Telnet to port 9999 again and
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 must 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 have
a network connection.
Make sure that the Link LED is lit.
If the Link LED is not lit, then the
device server does not have a
network connection.
The device server is not
communicating with the serial
device it is attached to.
The most likely reason is the
wrong serial settings were
chosen.
The serial settings for the serial
device and the device server must
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.
When you try to enter the setup
mode on the device server via
the serial port, you get no
response.
The issue is most likely
something covered in the
previous problem, or possibly,
you have Caps Lock on.
Double-check everything in the
problem above. Confirm that
Caps Lock is not on.
You can ping the device server,
but not Telnet to the device
server on port 9999.
There may be an IP address
conflict on your network

Turn the device server off and
then issue the following
commands at the DOS prompt of
your computer:
