Cables and connectors
Status LED, one bicolor:
•
Off—PIC ports not enabled.
•
Green—PIC is operating normally.
•
Red—PIC has an error or failure.
4-port PIC—One pair of port LEDs:
•
Link LED—If green, the port is online; if there is no light, the port is down.
•
RX LED—If flashing green, the port is receiving data; if there is no light, the port might be on but
is not receiving data.
8-port PIC—one pair of port LEDs per port:
•
Port link LED—If green, the port is online; if there is no light, the port is down
NOTE: The link LED remains lit on the 8-port PIC when the port is down.
•
Port RX LED—If flashing green, the port is receiving data; if there is no light, the port might be
on, but is not receiving data
12-port PIC—one port LED per port:
•
Green—100-Mbps link established
•
Flashing green—100-Mbps activity
•
Yellow—10-Mbps link established
•
Flashing yellow—10-Mbps activity
•
Off—No link present
NOTE: The port LEDs remain lit on the 12-port PIC when the ports are down.
