E320 8.1.x Module Guide

Cables and connectors	■	Up to four LC-style fiber-optic connectors
(single-mode [ZX] )	■	Transmit power:
		■	min: –2 dBm
		■	max: 3 dBm
	■	Receive input power:
		■	min: –22 dBm
		■	max: –3 dBm
	■ See the following corresponding table (ZX Fiber Optic Cabling) for cabling
		requirements.
	■ See E320 Hardware Guide, Chapter 5, Cabling the Router for more information.
LEDs	When lit, LED indicates:
	■ OK (green)—Physical link is connected properly and is functioning properly
	■ FAIL (red)—Failure detected
	■	Port LEDs:
		■ LK (green)—Ethernet link is up
		■ ACT (green)—Blinks when there is Ethernet traffic being received
Alarms, errors, and events	■	See Monitoring Ethernet Interfaces in JUNOSe Physical Layer Configuration Guide,
		Chapter 5, Configuring Ethernet Interfaces.
