Configuring PoE Power Management

Configuring PoE Power Management

Context

The maximum output power of the device is determined by the PoE power supply backup mode, PoE-capable module quantity, type, and input voltage. You can configure the maximum power, percentage of PoE power to be reserved, PoE power alarm threshold, and maximum power on each interface. Setting power parameters based on the requirements of PDs connected to the device helps effectively use PoE power and ensures device stability.

Procedure

  • Configure the PoE power supply backup mode.

    If a chassis PoE device is equipped with multiple power supplies and the power is sufficient, configure some power supplies as backup power supplies. If the active power supply is faulty, the backup power supply will continue to provide power for PDs, ensuring system stability.

    1. Run system-view

      The system view is displayed.

    2. Run poe-power backup-mode backup-mode

      The PoE power supply backup mode is configured.

      By default, the device has no PoE power supply backup.

      NOTE:
      The S9303 has only one PoE power supply slot and does not support the PoE power supply backup mode.

  • Configure the maximum output power of the devicecard.

    The quantity and power requirements of PDs connected to each card are different. In addition, the total power of the device may fluctuate. To solve this problem, you can configure the power for each card to provide a fixed amount of power for each card.

    1. Run system-view

      The system view is displayed.

    2. Run poe max-power max-power slot slot-id

      By default, the maximum output power provided by a PoE board is dynamically adjusted according to the number of installed PoE power modules and the input voltage.

      By default, the maximum power of each card is the average power that is allocated from the maximum power of the device.

  • Configure the maximum output power for an interface.

    The PD power negotiation result may be different from the power required by non-standard PDs or PDs that cannot be classified. You can configure the maximum output power of an interface to prevent power overload for PDs and save energy.

    An interface provides 15400 mW power to PDs based on the power class 0 if non-standard PDs are connected to the interface.

    1. Run system-view

      The system view is displayed.

    2. Run interface interface-type interface-number

      The interface view is displayed.

    3. Run poe power port-max-power

      The maximum output power is configured for the interface.

      By default, the maximum output power of an interface is 37000 mW.

  • Configure the percentage of PoE power to be reserved.

    The power of a PD continually changes while the PD is running. Sometimes, the power consumption increases sharply and the available power of the device cannot support the burst increase of power. If the device does not detect this problem and cuts off PDs on low-priority interfaces, all PDs will be powered off due to overload. You can configure reserved power to solve the problem. When power consumption increases sharply, the reserved power can support the running of the system. The device can immediately power off PDs on low-priority interfaces to ensure that other PDs continue to run stably.

    1. Run system-view

      The system view is displayed.

    2. Run poe power-reserved power-reserved

      The percentage of the PoE power to be reserved is configured.

      By default, the percentage of the reserved PoE power against the total PoE power is 20%.

  • Configure the alarm threshold for the percentage of power consumption.

    When power consumption increases sharply, the reserved power can often satisfy power requirements. However, if power consumption exceeds the safe range, some PDs will still be powered off. To solve this problem, configure an alarm threshold for the percentage of power consumption. When power consumption exceeds this threshold, the system generates an alarm, alerting administrators to take measures to reduce power consumption.

    1. Run system-view

      The system view is displayed.

    2. Run poe-power utilization-threshold threshold-value

      The alarm threshold for the percentage of power consumption is configured.

      By default, the alarm threshold is 90%. An alarm is generated when the consumed power accounts for 90% of the total power.
