12-port PIC:
- Very High Density Connector Interface (VHDCI) to RJ-21 cable that connects to an RJ-45 patch panel
LEDs Status LEDs, one bicolor:
- Off—PIC ports not enabled
- Green—PIC is operating normally
- Red—PIC has an error or failure
4-port and 8-port PICs have port LEDs, one pair per port:
- Link—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.
- RX—If flashing green, the port is receiving data; if there is no light, the port might be on, but is not receiving data
The 12-port PIC have port LEDs, one 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.
