Problem/Message Error Remedy
The MPS is
connected to a power
source, but there is
no LED activity. The unit or its power
supply is damaged. Contact your dealer or
Lantronix Technical
Support for a replacement.
The MPS is unable to
complete power-up
diagnostics. This generally
indicates a hardware
fault. One of the LEDs
will be solid red for
three seconds,
followed by one
second of another
color. Note the blinking LED and
its color, then contact your
dealer or Lantronix
Technical Support. The
MPS will not be
operational until the fault
is fixed.
A rapidly blinking OK
LED may signal boot
failure.
Reboot the unit. When the
MPS is running normally,
the
OK LED blinks every
two seconds.
The MPS passes
power-up diagnostics,
but attempts to
download new Flash
ROM code from a
network host. If the OK LED blinks
rapidly, the Flash ROM
code may be corrupt.
If you did not request a
TFTP boot, the flash
ROM code is corrupt.
The unit will remain in
boot mode. Reboot the unit. If you get
the same message, you
will need to reload Flash
ROM. See
Reloading
Software on page D-2.
