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;=All&pf;=MX+Series.


OK/FAIL LED, one bicolor:

  • Green—MIC is functioning normally.

  • Red—MIC has failed.

Link LED, one green per port:

  • Off—No link.

  • On steadily—Link is up.
