Power over Ethernet (PoE) allows ICX switches to deliver electrical power to connected devices over standard Ethernet cables. The amount of power provided is determined by the PoE class assigned to the port.
To supply a maximum of 15.4W to a connected device, the port should be configured to PoE Class 3.
PoE Power Classes:
* Class 0: 0.44W to 12.95W
* Class 1: 0.44W to 3.84W
* Class 2: 3.84W to 6.49W
* Class 3: 6.49W to 15.4W
* Class 4: 15.4W to 30W (PoE+)
Configuration Steps:
* Access the Switch's CLI:
* Connect to the switch via console or SSH to access the Command Line Interface (CLI).
* Enter Global Configuration Mode:
enable
configure terminal
* Navigate to the Specific Interface:
* Replace 1/1/1 with the appropriate interface identifier.

* Set the PoE Power Class:
* Configure the port to provide power corresponding to Class 3.

Verification:
* Check PoE Status:
* To verify the PoE status and power allocation on the configured port, use:
show inline power
* This command displays the current PoE status, power consumption, and class information for each port.
Considerations:
* Device Compatibility:
* Ensure that the connected device is compatible with PoE Class 3 and does not require more than
15.4W.
* Power Budget:
* Monitor the switch's total PoE power budget to prevent over-subscription when multiple devices are connected.
