other end of the power cord into an electric service outlet and the power will be ready.
Power Notice:
The device is a power-required device, which means it will not work till it is powered. If your networks
should be active all the time, please consider using UPS (Uninterrupted Power Supply) for your device.
It will prevent you from network data loss or network downtime. In some areas, installing a surge
suppression device may also help to protect your PoE Web Smart Switch from being damaged by
unregulated surge or current to the Switch or the power adapter.
