LED Operation

Each McBasic-Gigabit Converter features diagnostic LEDs that provide information on

FiberAlert (FA)
FiberAlert minimizes the
problems associated with the
loss of one strand of fiber. If a
strand is unavailable, the B&B
Electronics device at the
receiver end notes the loss of
link. The device will then stop
transmitting data and the link
signal until a signal or link pulse
is received. The result is that the link LED on BOTH sides of the fiber connection will
go out indicating a fault somewhere in the fiber loop. Using FiberAlert, a local site
administrator is notified of a fault and can quickly determine where a cable fault is
located.
WARNING
Enable FiberAlert on one side of a media conversion only. Enabling it on both
sides would keep both transmitters off indefinitely.
