Tip: You
can use the Hardware
Compatibility Tool to find information about the pluggable
transceivers supported on your Juniper Networks device.
The list of supported transceivers for the MX Series is located
at https://pathfinder.juniper.net/hct/category/#catKey=100001&modelType;=All&pf;=MX+Series.
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 CLI Explorer.

LEDs
|
OK LED, one tricolor:
Off—PIC is offline and safe to remove from the router
Green—PIC is operating normally
Yellow—PIC is initializing
Red—PIC has an error or failure
APP LED, one green per port:
Port 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
