Cables and connectors

4-port PIC:

  • Connector: Two-pair, Category 5 unshielded twisted-pair connectivity through an RJ-45 connector
  • Pinout: MDI noncrossover

8-port PIC:

  • Connector: MT-RJ female
  • FX optical interface—see Table 8

12-port PIC:

  • Connector: One very High Density Connector Interface (VHDCI) to RJ-21 cable that connects to an RJ-45 patch panel
  

LEDs

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.
