Juniper Networks M120 manual Cables and connectors, LEDs

M120 Internet Router PIC Guide

Cables and connectors	■ Duplex SC/PC connector (RX and TX)
	■ Optical interface support—See Table 19 on page 74 and Table 20 on page 75
LEDs	Status LED, one bicolor:
	■ Off—PIC not enabled
	■ Green—PIC is operating normally
	■ Red—PIC has an error or failure

Port LEDs, one pair:

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

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