Configure PoE Globally
About this task
Configure PoE usage threshold and device type settings, and enable Fast PoE and Perpetual PoE globally on a switch.

Important
- 
                        
After you enable Fast PoE or Perpetual PoE or both, you must save the running configuration file.
 - 
                        
If Fast PoE or Perpetual PoE are enabled and you change any other global or port-specific PoE settings, you must resave the running configuration file.
 
Procedure
- In the navigation pane, expand .
 - Select Chassis.
 - Select the PoE tab.
 - For Usage Threshold%, type the value in percentage for comparing the measured power.
 - For PoweredDeviceDetectType, select the PoE detection type depending on the capabilities of the switch.
 - Select FastPoeEnable.
 - Select PerpetualPoeEnable.
 - Select Apply.
 
PoE Field Descriptions
Use the data in the following table to use the PoE tab.
| 
 Name  | 
 Description  | 
|---|---|
| 
 Power(watts)  | 
 Specifies the nominal power of the Power Sourcing Entity expressed in Watts.  | 
| 
 OperStatus  | 
 Specifies the operational status of the main Power Sourcing Entity.  | 
| 
 ConsumptionPower(watts)  | 
 Specifies the measured usage power expressed in Watts.  | 
| 
 UsageThreshold%  | 
 Configures the usage threshold in percent for comparing the measured power and initiating an alarm if the threshold is exceeded.  | 
| 
 PoweredDeviceDetectType  | 
 Configures the mechanism used to detect powered ethernet devices attached to a powered ethernet
                                port. The options are: 
 Note: 
                                     
The default detection type is automatically configured for the highest PoE standard supported on the switch.  | 
| 
 PowerPresent  | 
 Specifies the current power source present on the switch. Available power sources are AC and DC. A value of acOnly indicates that the only power supply is AC. A value of dcOnly indicates that the only power supply is DC. A value of acDc indicates that the two power supplies, AC and DC are supplying power.  |
