  Optical interface specifications—see SONET/SDH OC3/STM1 Optical Interface Specifications

Note: To extend the life of the laser, when a PIC is not being actively used with any valid links, take the PIC offline until you are ready to establish a link to another device. For information about taking a PIC offline, see the request chassis pic offline command in the Junos System Basics and Services Command Reference.

LEDs

One tricolor per port:

• Off—Not enabled
• Green—Online with no alarms or failures
• Yellow—Online with alarms for remote failures
• Red—Active with a local alarm; router has detected a failure
