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 Managed Switch from being damaged by unregulated
