Connect To Ground - TP-Link JetStream T2500G-10MPS Installation Manual

3.2 Connect to Ground

Connecting the device to ground is to quickly release the lightning over-voltage and
over-current of the device, which is also a necessary measure to protect the body
from electric shock.
In different environments, the device may be grounded differently. The following
will instruct you to connect the device to the ground in two ways, connecting to the
ground via the power supply or connecting to the ground via the grounding terminal.
Please connect the device to ground in the optimum way according to your specific
operation environment.
Note:
For the device without grounding terminal, please refer to the first way Connecting to
the Ground via the Power Supply only.
Connecting to the Ground via the Power Supply
