Configuring PoE or PoE+
Configuring PoE or PoE+ is a two-step process:
1 Connect the IEEE 802.3af/802.3at-compliant powered device directly to a port.
2 Enable PoE or PoE+ on the port extender.
Enabling PoE or PoE+ on a Port
By default, PoE or PoE+ are disabled.
Configuration tasks for PoE include:
• Enabling PoE and managing the inline power supplied to the port extender ports using the power
inline mode command. To manage inline power in a port extender, use Configure Class or Static
mode. See
Configure Power Management Mode (Class and Static Mode).
• Limiting the maximum amount of power (in milliwatts) available to a powered device using the power
inline {[max_milliwatts] | priority {critical | high | low}} command. See
Allocating PoE Power on a PE and Determining the Power Priority for a Port.
