Cables and connectors

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:

  • Off—Service is not running

  • Green—Service is running under acceptable load

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
