Software features

Interfaces

Syntax: mediatype-fpc/pic/port where:

  • mediatype: ge or xe

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

  • pic:

    • ge: 0 or 1

    • xe: 2 or 3

  • port:

    • ge: 0 through 9

    • xe: 0

For example, xe-1/3/0 is the interface for the port labeled PORT 3/0 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.

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.

TUNNEL LED, one green per XFP port:

  • Off—Normal operating mode.

  • On steadily—Port configured in tunnel mode.

The SFP Link LEDs are labeled in groups of five:

  • 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

The XFP ports are labeled top to bottom 2/0 and 3/0.
