You can install any transceiver supported by the PIC. For information about installing
and removing transceivers, see the PIC and Transceiver Installation Instructions.

■

Fiber-optic SFP transceivers:

■

Duplex LC/PC connector (Rx and Tx)

■

Optical interface support—See Table 20 on page 46

■

1000Base-T SFP transceivers:

■

Connector: Four-pair, Category 5 shielded twisted-pair connectivity through an RJ-45
connector

■

Pinout: MDI crossover

■

Length: 328 ft/100 m

NOTE: Do not install Gigabit Ethernet SFPs in the SONET/SDH port. The port will not recognize
the SFP.

Cables and connectors

Status LED, one bicolor:

■

Off—PIC is not enabled

■

Green—PIC is operating normally

■

Red—PIC has an error or failure

Port LEDs, one pair per port:

■

Link—If green, the port is online; if there is no light, the port is down

■

Activity—If flashing green, the port is receiving data; if there is no light, the port might
be on but is not receiving data
