(flashing amber, blinking green, or solid green). If the RX LED is off

until it is on:
a. Ensure that the power is turned on for the device at the other end
of the link.
b. Verify that the fiber connections between the applicable port on
the 6H12X-08 and fiber optic device on the other end of the fiber
optic link segment are properly crossed over.
NOTE
During the bootup process, the RX LED flashes green and
amber, and will not indicate if a link exists until bootup is
complete.
