Chassis

  • 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, number-of-ports, and MICs Supported by MX Series Routers.]

  • Support for thermal health check and PSM watchdog features (QFX10002)—Starting in Junos OS Release 24.2R1, thermal health check is supported on QFX10002 switches. You can configure an action to be taken on detection of a thermal health event such as power leakage. You can enable PSM watchdog feature as well.

    [See thermal heath check and watchdog (PSM).]

  • Resiliency support (SRX2300)—Starting in Junos OS Release 24.2R1, the resiliency feature is enabled for the following hardware components:

    • CPU

    • Peripheral Component Interconnect (PCI)

    • Memory

    • Inter-Integrated Circuit (I2C)

    • Temperature sensor

    • Two power supply units (PSUs) in 1+1 redundancy mode

    • Fan

    Resiliency feature monitors the platform components periodically, performs alarm management, and takes corrective actions if an anomaly is persistently encountered.

    [See Chassis-Level User Guide.]

  • 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.
