Problem/Message Error
The EPS is
connected to a power
source, but there is
no LED activity.
The EPS is unable to
complete power-up
diagnostics.
The EPS completes
its power-up and
boot procedures, but
there's no noticeable
serial activity.
B-2
The unit or its power supply is
damaged.
This generally indicates a
hardware fault. One of the
LEDs will be solid red for three
seconds, followed by one
second of another color.
There is a problem with the
serial connection or the set-up
of the serial device.
A rapidly-blinking OK LED
may signal boot failure.
Remedy
Contact your dealer or Lantronix
Technical Support for a replacement.
Note the blinking LED and its color, then
contact your dealer or Lantronix
Technical Support. The EPS will not be
operational until the fault is fixed.
Check the terminal setup and the physical
connections, including the cable pinouts
(see Appendix C). Try another serial
device or cable, or cycle power on the
EPS.
Reboot the unit. When the EPS is running
normally, the OK LED blinks every two
seconds.
