■

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

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

■

Fiber-optic small form-factor pluggable transceivers (SFPs):

■

Duplex LC/PC connector (Rx and Tx)

■

Optical interface support—See Table 22 on page 53

■

Copper 1000Base-T SFPs:

■

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

■

Pinout: MDI crossover

■

Length: 328 ft/100 m

OK or Status LED, one tricolor:

■

Off—PIC is offline and it is safe to remove it from the router.

■

Green—PIC is operating normally.

■

Amber—PIC is initializing.

■

Red—PIC has an error or failure.

APP LED, one bicolor:

■

Off—Monitoring application is not running.

■

Green—Monitoring application is running under acceptable load.

Port LEDs, one per port:

■

Off—Port is not enabled.

■

Green—Port is online with no alarms or failures.
