PoE Settings
The Switch supports both the IEEE 802.3af Power over Ethernet (PoE) and IEEE 802.3at High Power over Ethernet (PoE) standards. The Switch is Power Sourcing Equipment (PSE) because it provides a source of power through its Ethernet ports, and each device that receives power through an Ethernet port is a Powered Device (PD).
Make sure your PoE Switch is using the latest firmware.Global Settings
In the navigation panel, click Configuration > Port > PoE > Global to display the screen. Use this screen to configure Power over Ethernet (PoE) global settings.
The following table describes the labels in this screen.
Label | Description |
|---|---|
PoE Mode | Select the power management mode you want the Switch to use. • Classification – Select this if you want the Switch to reserve the maximum power for each PD according to the PD’s power class and priority level. If the total power supply runs out, PDs with lower priority do not get power to function. In this mode, the maximum power is reserved based on what you configure in Max Power or the standard power limit for each class. • Consumption – Select this if you want the Switch to supply the actual power that the PD needs. The Switch also allocates power based on a port’s Max Power and the PD’s power class and priority level. The Switch puts a limit on the maximum amount of power the PD can request and use. In this mode, the default maximum power that can be delivered to the PD is 33 W (IEEE 802.3at Class 4) or 22 W (IEEE 802.3af Classes 0 to 3). |
Pre-Allocate | This field is only available on GS1900-8HP (Revision B1) and GS1900-10HP only. Select Enable to have the Switch pre-allocate power to each port based on the classification of the PD device. This allows the Switch to prepare the reserve power to meet the power budget before powering up the connected PD. Otherwise, select Disable. |
Power Up Sequence Delay | Select Enable to allow the PoE ports to be powered up one-by-one randomly. Alternatively, select Disable to allow all PoE ports to be powered up at the same time. When multiple PDs are connected to the Switch simultaneously, enable Power Sequence Delay to ensure power stability and continuity. |

Port Settings
Use this screen to view Switch port PoE settings and select ports for configuration. Click Configuration > Port > PoE > Port.
The following table describes the labels in this screen.
Label | Description |
|---|---|
Edit | Select one or more ports in the first column of the table and click this to configure PoE settings for the ports. |
Port | Displays the port index number. |
State | Displays which ports can receive power from the Switch. You can set this in the Configuration > Port > PoE Edit screen. • Disable – The powered device (PD) connected to this port cannot get power. • Enable – The PD connected to this port can receive power. |
Class | This shows the power classification of the PD. Each PD has a specified maximum power that fall under one of the classes. The Class is a number from 0 to 4, where each value represents the range of power that the Switch provides to the PD. The power ranges for each class 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) in a switch that supports IEEE 802.3af only. Optional, 12.95 to 25.50 in a switch that supports IEEE 802.3at. |
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. • Medium has the Switch assign power to the port after all critical and high priority ports are served. • Low has the Switch assign power to the port after all critical, high and medium priority ports are served. |
Power-Up | This shows how the Switch provides power to the connected PD at power-up. 802.3af – the Switch follows the IEEE 802.3af Power over Ethernet standard to supply power to the connected PDs during power-up. Legacy – the Switch can provide power to the connected PDs that require high inrush currents at power-up. Pre-802.3at – the Switch initially offers power on the port according to the IEEE 802.3af standard, and then switches to support the IEEE 802.3at standard within 75 milliseconds after a PD is connected to the port. Select this option if the Switch is performing 2-event Layer-1 classification (PoE+ hardware classification) or the connected PD is NOT performing Layer 2 power classification using Link Layer Discovery Protocol (LLDP). 802.3at – the Switch supports the IEEE 802.3at High Power over Ethernet standard and can supply power of up to 30W per Ethernet port. IEEE 802.3at is also known as PoE+ or PoE Plus. An IEEE 802.3at compatible device is referred to as Type 2. Power Class 4 (High Power) can only be used by Type 2 devices. If the connected PD requires a Class 4 current when it is turned on, it will be powered up in this mode. |
Wide Range Detection | This field is available on GS1900-8HP (Revision B1) and GS1900-10HP only. This shows whether the Switch enables a wider detection range for the PD or not. The Switch detects whether a connected device is a powered device or not before supplying power to the port. For the PD detection, the Switch applies a fixed voltage to the device and then receives returned current. If the returned current is within the IEEE 802.3AF/AT standard range, the device will be considered as a valid PD by the Switch. However, in real cases, environmental interferences might easily cause the returned current out of the standard range. This field displays Enable if the Switch applies a wider range for PD detection. Otherwise, it displays Disable. |
Consuming Power (mW) | This field displays the current amount of power consumed by the PD from the Switch on this port. |
Max Power (mW) | This field displays the maximum amount of power the PD could use from the Switch on this port. |
Time Range | |
Name | This field displays the name of the time range (schedule) rule which is applied to the port. PoE is enabled at the specified time or date. |
Status | This field displays whether the port can receive power from the Switch (In) or not (Out) currently. It shows – if there is no schedule applied to the port. |
