SDS1100 User Guide
5: Troubleshooting
Problem/Message
Reason
Solution
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 SDS.
The SDS 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 SDS
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. Tip: You cannot
assign an IP address to a SDS
through a router.
No LEDs are lit.
The unit or its power supply is
damaged, or the unit is not plugged
into power properly.
Try plugging the SDS into another
outlet. If this does not fix the
problem, contact your dealer or
Lantronix Technical Support for a
replacement.
The SDS1100 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 SDS is not communicating with
the serial device attached to the SDS.
The most likely reason is the wrong
serial cable or serial settings were
chosen.
Make sure that you are using the
correct serial cable. The SDS serial
port is just like a modem serial port
(DCE). The serial settings for the
serial device and the SDS must
match. The default serial settings for
the SDS 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 SDS via the serial cable, 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.
