Conguring PoE or PoE+
Conguring 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.
Conguration 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 Congure Class or Static mode. See
Congure 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.
Conguration Tasks for PoE or PoE+
This chapter describes how to congure and manage the PoE or PoE+ feature on C1048P, N2024P, N2048P, N3024P, and N3048P PE
ports.
Conguration tasks for PoE include:
• Conguring Power Management Mode - Class and Static Mode
• Managing Ports using Power Priority and the Power Budget
• Allocating PoE Power to Power Devices to a Connected PE Interface
• Setting the Global Threshold limit PoE Power Budget
• Detecting and Allocating Power for Legacy Powered Devices
• Advertising Extended Power Though dot3–TLVs
• Advertising the Extended Power through MDI
• Deploying VOIP
• Managing PoE on a PE
• Upgrading the PoE Controller
• Stopping and Restarting Power Delivery
• Monitoring the Power Budget
• Display Power Consumption on the Port Extender
• Displaying PoE Power Allocation to Power Devices
