6x40GE + 24x10GE MPC5E

Software release

  • Junos OS Release 13.3R2 and later


  • Fixed-port MPC with six 40-Gigabit Ethernet ports and twenty-four 10-Gigabit Ethernet ports

  • Weight: 21 lb (9.52 kg)

  • Model number: MPC5E-40G10G

  • Name in the CLI: MPC5E 3D 24XGE+6XLGE

Hardware features

  • Line-rate throughput of up to 240 Gbps

  • Supports one of the following port combinations:

    • Six 40-Gigabit Ethernet ports

    • Twenty-four 10-Gigabit Ethernet ports

    • Three 40-Gigabit Ethernet ports and twelve 10-Gigabit Ethernet ports

  • Supports up to 32,000 queues per-slot

  • LAN-PHY mode at 10.3125 Gbps on a per-port basis

  • WAN-PHY mode at 9.95328 Gbps on a per-port basis

  • Supports maximum transmission unit (MTU) size of 9,192 bytes for host bound packets. For Junos OS 16.1R1 and later releases, the MTU size supported is 9,500 bytes.

  • The ports are labeled as:

    • 10-Gigabit Ethernet ports:

      0/0 through 0/11

      1/0 through 1/11

    • 40-Gigabit Ethernet ports:

      2/0 through 2/2

      3/0 through 3/2

  • The MPC5E supports the enhanced Switch Control Board (MX-SCBE) and MX-SCBE2 on MX240, MX480, and MX960 routers. The MPC5E does not support the legacy SCB (MX-SCB). The MPC5E supports the Switch Fabric Board (SFB) on MX2010 and MX2020 routers.

  • MPC5E does not interoperate with the existing DPCs, except the Multiservices DPC (MS-DPC).


On the MX960 router, all the MPC slots work in a chassis temperature of up to 40°C (104°F), at an altitude of up to 6000 feet. However, when the chassis temperature exceeds 40°C (104°F),

  • the slot 11 does not work with MPC3E-3D-NG, MPC3E-3D-NG-Q, MPC4E, and MPC5E.

  • the slot 0 does not work with MPC4E and MPC5E.

Software features

  • Optical diagnostics and related alarms

  • Support for optical transport network (OTN) on 10-Gigabit Ethernet ports

  • Two packet-forwarding engines, PFE0 and PFE1. PFE0 hosts PIC0 and PIC2. PFE1 hosts PIC1 and PIC3.

  • Configurable LAN-PHY and WAN-PHY mode options per 10-Gigabit Ethernet port

  • See Protocols and Applications Supported by the MPC5E for MX Series Routers for information about the protocols and applications that this MPC supports.


On MX240, MX480, and MX960 routers, MPC5E powers on only if the network-services mode on the router is configured to either enhanced-ip or enhanced-ethernet. On MX2010 and MX2020 routers, only enhanced-ip is supported.


A maximum of two PICs can be powered on at any one time (PIC0 or PIC2, and PIC1 or PIC3). The other PICs must be powered off.

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.


QSFPP-40GE-LX4 is not NEBS compliant on the MX960 router in FPC slot 0 or FPC slot 11.
