1. The device is a power-required device, it means, it will
not work till it is powered. If your networks should 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.
2. In some area, installing a surge suppression device may
also help to protect your converter from being damaged
by unregulated surge or current to the converter or the
power adapter.
