  • 10x10GbE SFPP and 10x1GbE SFP MIC support (MX240, MX480, MX960, MX2010, and MX2020 routers)—Starting in Junos OS Release 24.2R1, the Modular Interface Cards (MICs) 10x10GbE SFPP and 10x1GbE SFP support the MPC2E-NG and MPC3E-NG line cards on the MX240, MX480, MX960, MX2010, and MX2020 routers. This new MIC has 10 ports that support 1-Gbps SFP and 10-Gbps SFP+ speeds along with Precision Time Protocol (PTP) and Media Access Control Security (MACsec) capabilities.

    [See pic-mode (MX Series) and number-of-ports.]

  • Support for Gen3 FT and FTC SKUs (MX-Series)—Starting in Junos OS Release 24.2R1, support is provided for the new fan trays (FT) (JNP10004 Fan-Tray Gen3 and JNP10008 Fan-Tray Gen3) and fan tray controllers (FTC) (JNP10004 Fan Controller Gen3 and JNP10008 Fan Controller Gen3) SKUs along with resiliency support for MX10004 and MX10008 devices.

  • Optics EM policy support (MX304)—Starting in Junos OS Release 24.2R1, we have extended the Junos Environment Monitoring (EM) policy to include optics temperature sensors for MX304 routers. It includes the following features:

    • The Optics EM policy incorporates periodically polled temperature readings of optical modules in the system to automatically manage the fan speed.

    • 100GbE and 400GbE optics firmware automatically triggers optics shutdown when the high-temperature threshold is breached.

    • EM policy is enabled by default on all 100GbE and 400GbE optics interfaces, except for loopback optics and direct attach copper (DAC) cables.

    You can use the set chassis fpc fpc_slot pic pic_slot port port_no no-temperature-monitoring command to explicitly disable the EM policy on specific WAN ports. Use the show chassis environment command to view the optics temperature.

  • Source Redundancy and Feed Redundancy support (MX10004 and MX10008)—N+1 power redundancy is supported on MX10004 and MX10008 routers with the JNP10K-PWR-DC3 power supply modules (PSMs). You can enable either source redundancy or feed redundancy for the PSM.

    [See Power Redundancy for Third-Generation Power Supply Modules.]

  • Resiliency support (MX10004 and MX10008)—We support resiliency for JNP10K-PWR-DC3 power supply modules (PSMs) on MX10004 and MX10008 devices. Resiliency enables the system to monitor component health, alert you of errors, and take appropriate action to restore normal operation based on error severity.
