On FOT-B, the
P1
LED indicates the status of the fiber ST port and the
P2

P1 And P2 LEDs For Station And Lobe Ports
The
P1

The table below describes the LED indications for ports configured as
lobe or station ports.
NOTE
The
P1
and
P2
LEDs act differently on FOTs configured for
station/lobe applications than they do for FOTs configured for
RI/RO applications.
