Licensing Requirements and Limitations for PoE

Licensing Requirements and Limitations for PoE

Powered devices (PDs)

Licensing Requirements

PoE is a basic feature of a switch and is not under license control.

Version Requirements

NOTE:

Only switches with "PWR" in the device names are PoE switches. Whether switches support PoE depends on the hardware. Non-PoE switches cannot be changed to PoE switches through software upgrades.

Feature Limitations

PoE Power Supplies Supported by the Switch
  • In the versions earlier than V100R005, all PoE power supplies are 250 W non-constant current power supplies. When two power supplies are used, they are used for power redundancy, but do not offer power.
  • In V100R005 and later versions, PoE power supplies include 250 W and 500 W constant current power supplies. When two 250 W or 500 W constant current power supplies are used, the power supplies can be used for power redundancy and offer power at the same time.
  • In V200R002 and later versions, PoE power supplies include 250 W, 500 W, 580 W, and 1150 W constant current power supplies. When two 580 W or 1150 W constant current power supplies are used, the power supplies can be used for power redundancy and offer power at the same time.
  • In V200R007 and later versions, PoE power supplies include 250 W, 500 W, 580 W, 650 W, and 1150 W constant current power supplies. When two 580 W, 650 W, or 1150 W constant current power supplies are used, the power supplies can be used for power redundancy and offer power at the same time.
  • In V200R013 and later versions, 1000 W constant current PoE power supplies are available . These power supplies can be used in the same switch as 580 W and 1150 W constant current power supplies. When two constant current power supplies are used, these power supplies can be used for power redundancy and provide power at the same time.
  • Downlink electrical interfaces of PoE switches provide PoE power and each interface supports a maximum of 200 m power supply distance. The PoE switch can transmit both current and data on a pair of signal cables.

  • For the available PoE power, maximum number of ports, and power module type provided by different PoE switch models, see "Chassis" in the Hardware Description of the specific switch model. PoE switches have "PWR" in the product names. For details about PoE power supply configuration, see "Power Supply Configuration" of the specific switch model.

PoE function
  • The switch supports power supply capability negotiation using the Link Layer Discovery Protocol (LLDP).
  • The switch supports perpetual power supply and fast power-on.
  • If a switch supports PoE, its PoE feature is not affected after it joins a stack.

  • The maximum PoE power supply distance is 100 m.
Restrictions on the PoE function
  • The switch can still power the attached PDs when they are reboot using the reboot command. After rebooting, a PD will be powered off and then on when all the following conditions are met:
    1. The PD can be powered on successfully.
    2. Forcible power supply has been enabled on the port connected to the PD or any of the other three ports that share the same PSE chip with this port, but the forcible power supply configuration has not been saved before the reboot.
  • If the switch power is sufficient but PDs cannot be powered on, try to use the poe force-power command to forcibly power on the PDs connected to interfaces.
  • On the , forcible PoE power supply and PD compatibility check are mutually exclusive, and different power supply modes are mutually exclusive on PoE interfaces.
