power remains to allocate to the next device. When less than 7W of PoE power is available
on a port, the port PoE LED lights yellow, and the attached device does not receive power
from the port. However, the switch continues to send data through the port connection.
The switch is also a smart switch in that it can override the IEEE power classification of a
powered device (PD): If the PD consumes less power than required by its power
classification, the
switch provides only the power that the PD consumes instead of the power
that is required by the PD’s power classification.
If some PoE+ ports are in use and deliver power, you can calculate the available power
budget for the other PoE+ ports by subtracting the consumed (that is, delivered power) from
the total
available power budget. (For information about the total available power budget, see
PoE concepts on page 92.)
An example for model GS110TPv3:
Port 1 delivers 4.4W to a PD. The available power budget is 50.6W (55W–4.4W).
An example for model GS110TPP:
A Class 4 PD is attached to Port 1, a Class 2 PD to Port 2, and another Class 4 PD to Port 3.
However, the PDs consume less power than defined by their classes: The PD attached to
Port 1 consumes 7.3W, the PD attached to Port 2 consumes 4.7W, and the PD attached to
Port 3 consumes 8.9W. So even though the switch provides power to two Class 4 devices
and one Class 3 device, if the default power adapter is installed, the available power budget
is 99.1W (120W–7.3–4.7–8.9W).
To determine the delivered power by a PoE+ port:
1. Connect
your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is off-network using an Ether
net cable.
2. Launch a web browser.
3. In the address field of your web browser, enter the IP address of the switch.
If you do not know the IP address of the switch, see
Access the switch on-network and
connected to the Internet on page 20 or Access the switch off-network and not
connected to the Internet on page 28.
The Device UI login page displays.
If you did not yet activate your warranty, the Register to activate your warranty page
displays. For more information, see
Register the switch on page 31.
4. Enter one of the following passwords:
• Enter your device admin password.
• If you previously managed the switch through the Insight app or
Cloud portal, enter
the Insight network password for the last Insight network location.
For information about the credentials, see
Credentials for the device UI on page 29.
5. Click the Go
button.
