Gigabit Ethernet Enhanced Queuing Ethernet Services DPC with SFP

Software release

  • Junos OS Release 8.5 and later


  • 40 Gigabit Ethernet ports

  • Power requirement: 7.6 A @ 48 V (365 W)

  • Weight: 13.1 lb (5.9 kg)

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

  • Model number: DPCE-X-Q-40GE-SFP

  • Name in the CLI: DPCE 40x 1GE X EQ

Hardware features

  • High-performance throughput on each port at speeds up to 1 Gbps

  • 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


The routing table is limited to 32,000 IP routes. This limitation applies to any manner in which the routes are learned, such as OSPF, RIP, and so on. The DPC supports BGP for L2 VPNs only.


Syntax: ge-fpc/pic/port where:

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

  • pic: 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-1/3/0 is the interface for port 0 in the top right row of 10 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.

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


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


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:

  • 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
