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.
Configuration Tasks for PoE or PoE+
This chapter describes how to configure and manage the PoE or PoE+ feature on C1048P PE ports.
Configuration tasks for PoE include:
• Configuring 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
For a complete listing of all PoE commands, see the Dell Networking OS Command Line Reference
Guide.
