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 Gigabit Ethernet 1000BASE 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

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