POST diagnostics
When the FSW-1607/2407TFX is powered up the POST (Power
On Self Test) is run. A series of built-in diagnostics are performed
to check that the system is functioning and configured correctly.
As the diagnostics are run, the LEDs on the FSW-1607/2407TFX
go on in sequence. If the LED does not go off, but instead flashes,
the diagnosis has failed and the POST will stop at the point of fail-
ure. Note the port number where the diagnosis failed and contact
your local authorized service technician.
