Problem/Message Reason Solution
When you try to assign an IP with
DeviceInstaller, you get the
following :
"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 to which it is attached. 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 using
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 Telneting 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 is
a duplicate IP address on the
network. If you do not get a
response, use the serial port to
verify that Telnet is not disabled.
With DeviceInstaller, you get the
Wrong Password
error when you try
to upgrade the firmware.
The file you are attempting
to load is the incorrect
firmware file for the UDS. Download the correct firmware file
from the Lantronix website.
