Overview of Energy-Saving Management

Overview of Energy-Saving Management

Purpose

The energy-saving management function reduces power consumption.

As network scales enlarge, power consumption increases, which increases operation costs. Energy saving is becoming a major concern in network construction.

Energy-Saving Management Features Supported by the Device

The device supports energy-saving features including intelligent fan speed adjustment, Energy Efficient Ethernet (EEE), and automatic laser shutdown (ALS).

  • Intelligent fan speed adjustment

    Intelligent fan speed adjustment enables the device to run at normal temperatures and reduces power consumption and noise. It monitors the temperature of key components and increases the fan speed if a sensitive component overheats. When the temperature falls back to its normal range, the fan speed is decreased.

  • ALS

    ALS protects operators against laser injury and saves energy. It controls the pulse of the laser of an optical module by detecting the Loss of Signal (LOS) on an optical interface.

    Without ALS, if an optical fiber link fails, data communication is interrupted but the optical interface and the laser of an optical module are still enabled. Energy is wasted and eyes of operators may be hurt. With ALS, the LOS is detected and the laser is disabled. When the faulty optical fiber link is recovered, the system detects that the LOS of the optical interface is cleared and enables the laser again.

  • EEE

    EEE reduces system power consumption by dynamically adjusting the electrical interface power according to network traffic volume.

    Without EEE, the system provides power to every interface, resulting in idle interfaces using as much power as used interfaces. Using EEE, power to idle interfaces is reduced and then restored when the interface becomes in use.

  • Port dormancy

    In port dormancy mode, the physical layer (PHY) chip on an electrical interface enters the low energy consumption mode to reduce power consumption. When the interface is not connected, major data transmission channels of the chip enter the dormancy state to save energy. When the interface is connected and traffic on the cable is detected, the PHY chip restores to its normal working state.

  • Energy-saving modes

    The device can run in the following energy-saving modes:
    • Standard mode

      Factory mode and default power saving mode.

    • Basic mode

      Components not in use are shut down or switched to the sleep mode when no services are configured or users are not online.

    • Deep mode

      Power consumption is dynamically adjusted for running services, and components not in use are shut down or switched to the sleep mode according to service requirements.

    NOTE:
    • The ALS, EEE, and port dormancy functions are disabled in standard mode by default.

    • The ALS, EEE, and port dormancy functions are enabled by default in basic or deep mode.
