Configuration options

In the default configuration, all ports in a switch covered in this guide are configured to support PoE operation. You can:

  • Disable or re-enable per-port PoE operation on individual ports to help control power usage and avoid oversubscribing PoE resources.

  • Configure per-port priority for allocating power in case a PoE device becomes oversubscribed and must drop power for some lower-priority ports to support the demand on other, higher-priority ports.

  • Manually allocate the amount of PoE power for a port by usage, value, or class.

  • Allocate PoE power based on the link-partner’s capabilities via LLDP.


The ports support standard networking links and PoE links. You can connect either a non-PoE device or a PD to a port enabled for PoE without reconfiguring the port.
