Chassis

  • Chassis management support (ACX7020)—The ACX7020 router supports these chassis management features:

    • Power Supply Module (PSM) redundancy on ACX7020 with AC power supply

    • Power feed redundancy on ACX7020 with DC power supply

    • Optics Environmental Monitoring (EM) policy for automatic fan speed management

    • Voltage and current monitoring for PSM management

    In extremely cold temperatures—for example, at –40 °F (–40 °C)—the router turns off fans and disables the EM policy. The router restarts operations when the temperature increases to 14 °F (–10 °C).

    We've also made the following CLI command updates:

    • show chassis power displays combined output for PSM0 and PSM1.

    • show chassis hardware displays PSMs as built-in.

    • show chassis environment psm displays PSM state and DC output status.

    [See show chassis power, show chassis hardware, show chassis environment psm, and Optics EM Policy Support.]

  • Resiliency support (ACX7020)—We support resiliency for platform components on ACX7020 routers. Resiliency enables the system to monitor component health, alert you of errors, and take appropriate action to restore normal operation based on error severity.
