Description
If the green light is
ON, communication is
normal.
If it is OFF, check the
SPI pins for
connection issues or
configuration
problems.
If the green light
flashes, the fiber optic
card is powered on.
If it does not light up,
check for poor
contact at the power
PIN.
If the green light is ON, the
fiber optic cards are
communicating normally.
If it is OFF, the
communication between the
cards has not been
established. Check whether
the fiber cables are
damaged.
If there is an error
in the optical fiber
communication,
the red light will be
ON.
