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 Fast Ethernet 100BASE-FX Optical Interface Specifications

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.
