M20 Internet Router PIC Guide

Cables and connectors	■ 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 SX, LX, and LH small form-factor pluggable transceivers (SFPs):
	■ Connector: Duplex LC/PC (Rx and Tx)
	■ Optical interface support—See Table 14 on page 54
	■ 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
LEDs	OK 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:

■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.
