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 on page 45

12-port PIC:

■

connects to an RJ-45 patch panel

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.
