Tri-Rate Enhanced Ethernet Services DPC

Software release


  • 40 autonegotiating 10BASE-T, 100.BASE-TX, or 1000BASE-T Megabit Ethernet ports

  • Power requirement: 6.67 A @ 48 V (320 W)

  • Weight: 14.5 lb (6.6 kg)

  • Supports large Ethernet frame sizes for more efficient throughput across the intra-POP network

  • Model number: DPCE-X-40GE-TX

  • Name in the CLI:

Hardware features

  • High-performance throughput on each port at speeds of 10 Mbps, 100 Mbps, or 1000 Mbps

  • Autonegotiation between Gigabit Ethernet circuit partners

  • Full-duplex mode

  • Maximum transmission units (MTUs) of up to 9192 bytes

  • Enhanced ASICs for increased performance and scalability of Layer 2 features

Software features


Syntax: ge-fpc/pic/port where:

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

  • pic: Grouping of 10-ports, numbered 0 through 3

  • port: 0 through 9

For example, ge-1/3/0 is the interface for port 0 (labeled 3/0) in the right-most grouping of ports on a DPC installed in slot 1.

Cables and connectors


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.

  • Connector: Four-pair, Category 5 shielded twisted-pair connectivity through an RJ-45 connector

  • Pinout:

    • Junos OS Release 9.1: MDI

    • Junos OS Release 9.2 and later: MDI, MDI crossover

  • Maximum distance: 328 ft/100 m


Do not use RJ-45 cables with strain-relief boots exceeding 1.5 mm from the bottom of the connector. Cable boots that exceed this measurement can damage the port.


OK/FAIL LED, one bicolor:

  • Steady green—DPC is functioning normally.

  • Blinking green—DPC is transitioning online or offline.

  • Red—DPC has failed.

ACT LED, one green per port:

  • Off—No active traffic.

  • Blinking—Link is active.

SPD LED, one bicolor:

  • Green—DPC is functioning in 1000BASE-T mode.

  • Yellow—DPC is functioning in 10BASE-T or 100BASE-TX mode.

  • Off—No link.

The ACT and SPD LEDs are located on either side of the ports labeled horizontally and top to bottom 0/0 through 3/9.
