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.
