Software features

Interfaces

Syntax: ge-fpc/pic/port where:

  • fpc: Slot in the router where the DPC is installed

  • pic:

    • 20-port: 0 (left row of 10 ports), or 1 (right row of 10 ports)

    • 40-port: 0 (bottom left row of 10 ports), 1 (bottom right row of 10 ports), 2 (top left row of 10 ports), or 3 (top right row of 10 ports)

  • port: 0 through 9

For example, ge-1/1/0 is the interface for port 0 in the (top for 40-port) right row of 10 ports on a DPC installed in slot 1.

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.

You can install any transceiver supported by the DPC. For information about installing and removing transceivers, see the hardware guide for your router.

Note: Do not install Gigabit Ethernet SFPs in the SONET/SDH port. The port will not recognize the SFP.

LEDs

OK/FAIL LED, one bicolor:

  • Steady green—DPC is functioning normally.

  • Blinking green—DPC is transitioning online or offline.

  • Red—DPC has failed.

Link LED, one green per port:

  • Off—No link.

  • On steadily—Link is active.

The Link LEDs are labeled in groups of five:

  • 20-port:

    • 0/0 for 0/0 through 0/4

    • 0/5 for 0/5 through 0/9

    • 1/0 for 1/0 through 1/4

    • 1/5 for 1/5 through 1/9

  • 40-port:

    • 0/0 for 0/0 through 0/4

    • 0/5 for 0/5 through 0/9

    • 1/0 for 1/0 through 1/4

    • 1/5 for 1/5 through 1/9

    • 2/0 for 2/0 through 2/4

    • 2/5 for 2/5 through 2/9

    • 3/0 for 3/0 through 3/4

    • 3/5 for 3/5 through 3/9
