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
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
