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 remains lit on the 12-port PIC when the ports are down.
