| LABEL | DESCRIPTION |
| |
| State | This field shows which ports can receive power from the Switch. You can | ||
|
| set this in Section 8.8.1 on page 87. | ||
|
| • Disable - The PD connected to this port cannot get power supply. | ||
|
| • Enable - The PD connected to this port can receive power. | ||
|
|
| ||
| Class | This shows the IEEE 802.3af power classification of the PD. | ||
|
| This is a number from 0 to 4, where each value represents a range of | ||
|
| power (W) and power current (mA) that the PD requires to function. The | ||
|
| ranges are as follows. |
| |
|
| • | Class 0 - Default, | 0.44 to 12.94 |
|
| • | Class 1 - Optional, | 0.44 to 3.84 |
|
| • Class 2 - Optional , 3.84 to 6.49 | ||
|
| • | Class 3 - Optional, | 6.49 to 12.95 |
|
| • Class 4 - Reserved (PSEs classify as Class 0) | ||
|
|
| ||
| PD Priority | When the total power requested by the PDs exceeds the total PoE power | ||
|
| budget on the Switch, you can set the PD priority to allow the Switch to | ||
|
| provide power to ports with higher priority first. | ||
|
| • Critical has the highest priority. | ||
|
| • High has the Switch assign power to the port after all critical priority | ||
|
|
| ports are served. |
|
|
| • Low has the Switch assign power to the port after all critical and high | ||
|
|
| priority ports are served. | |
|
|
| ||
| Consuming | This field displays the current amount of power consumed by the PD from | ||
| Power (mW) | the Switch on this port. | ||
|
|
| ||
| Max Power | This field displays the maximum amount of power the PD could use from | ||
| (mW) | the Switch on this port. | ||
|
|
| ||
| Max Current | This field displays the maximum amount of current drawn by the PD from | ||
| (mA) | the Switch on this port. | ||
|
