4.5.3 P1 And P2 - Ports

Each FOT has P1 and P2 LEDs to indicate the status of the associated
port.
On FOT-A, the P1 LED indicates the status of the RJ45 Port, and the
P2 LED indicates the status of the fiber ST Port.
On FOT-B, the P1 LED indicates the status of the fiber ST Port, and the
P2 LED indicates the status of the RJ45 Port.
The P1 and P2 LEDs act differently on FOTs configured for
NOTE
station/lobe applications than they do for FOTs configured for
RI/RO applications.
P1 And P2 LEDs For Station And Lobe Ports
The P1 and P2 LED indications vary slightly for fiber ST and RJ45 ports.
