Troubleshooting

Problem/Message

Reason

Solution

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.

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.

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.

When you try to assign an IP
with DeviceInstaller, you get the
following message:

No response from device!
Verify the IP, Hardware
Address and Network Class.
Please try again

.

The cause is most likely one of
the following:

The Hardware address you
specified is incorrect.

The IP address you are trying to
assign is not a valid IP for your
logical subnet.

You did not choose the correct
subnet mask.

Double-check the parameters that
you specified.

Note:

You cannot

assign an IP address to a device
server through a router

.

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

You are not Telnetting to port
9999.

The Telnet configuration port
(9999) is disabled within the
device server security settings.

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

ARP -D X.X.X.X (X.X.X.X is the IP
of the device server).

PING X.X.X.X (X.X.X.X is the IP
of the device server).
If you get a response then there
