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 OS System Basics
and Services Command Reference.
