Use this screen to set the PoE settings for the Nebula Device. To access this screen, click the edit icon next to PoE Status in the Switch > Monitor > Switches: Switch Details screen.
To set PoE settings for an individual port, such as schedule, priority, and power mode, edit the Nebula Device’s port settings. For details, see Switch Ports.Switch > Monitor > Switches: Switch Details: PoE Configuration
The following table describes the labels in this screen.
Label | Description |
|---|---|
PoE Mode | Select the power management mode you want the Nebula Device to use. Classification mode – Select this if you want the Nebula Device to reserve the Max Power (mW) to each powered device (PD) according to the priority level. If the total power supply runs out, PDs with lower priority do not get power to function. Consumption mode – Select this if you want the Nebula Device to manage the total power supply so that each connected PD gets a resource. However, the power allocated by the Nebula Device may be less than the Max Power (mW) of the PD. PDs with higher priority also get more power than those with lower priority levels. |
