OC-12c and OC-48c Ports
The OC-12c/OC-48c POS interface modules support 2, 4, or 8 ports. Into a physical port, you must insert an
optical transceiver provided by Foundry.
The following SFP optical transceivers are available from Foundry for use with the The OC-12c /OC-48c POS
interface modules:
TX Pkt
center of board:
•
2nd from top
position
One LED per-port
as defined by
column position
Blinking Green
Blinks during transmission of packets from the
specified port.
Off
No packets are being transmitted from the
specified port.
Rx Pkt
center of board:
•
3rd from top
position
One LED per-port
as defined by
column position
Blinking Green
Blinks during reception of packets on the
specified port.
