Various 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. When you try to enter the setup The issue will most likely be mode on the device server via something covered in the the serial port, you get no previous problem, or possibly response. you have Caps Lock on. You can ping the device server, There may be an IP address but not Telnet to the device conflict on your network server on port 9999. You are not Telneting to port 9999. The Telnet configuration port (9999) is disabled within the device server security settings. A network device, such as a router, is blocking port 9999. With Device Installer you get the "Wrong Password" error when you try to upgrade the firmware. You have chosen the incorrect setting for the Existing Firmware field. Solution Change power supplies. Consult the LEDs section in the Introduction chapter or the Quick Start for the LED flashing sequence patterns. Call Lantronix Technical Support if the blinking pattern indicates a critical error. The serial settings for the serial device and the device server must match. The default serial settings for the device server are RS232, 9600 Baud, 8 Character Bits, No Parity, 1 Stop Bit, No Flow Control. Double-check everything in the problem above. Confirm that Caps Lock is not on. 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 (the LEDs on the device server should flash a sequence that tells you this). If you do not get a response, use the serial port to verify that Telnet is not disabled. Try upgrading the firmware again, but make sure to use the correct setting in the field of Existing Firmware field. 6-4 DSTni-XPress DR User Guide

Troubleshooting
Problem/Message
Reason
Solution
No LEDs are lit.
The unit or its power supply is
damaged.
Change power supplies.
The device server will not
power up properly, and the
LEDs are flashing.
Various
Consult the LEDs section in the
Introduction chapter or the Quick
Start for the LED flashing
sequence patterns. Call Lantronix
Technical Support if the blinking
pattern indicates a critical error.
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 RS232,
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 will most likely be
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.
A network device, such as a
router, is blocking port 9999.
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 (the LEDs on the device
server should flash a sequence
that tells you this). If you do not
get a response, use the serial port
to verify that Telnet is not
disabled.
With Device Installer you get
the “Wrong Password” error
when you try to upgrade the
firmware.
You have chosen the incorrect
setting for the
Existing
Firmware
field.
Try upgrading the firmware again,
but make sure to use the correct
setting in the field of
Existing
Firmware
field.
