■ AC Power Receptacle
For compatibility with electric service in most areas of the world, the Managed Switch’s power supply automatically
adjusts to line power in the range of 100-240V AC and 50/60 Hz.
Plug the female end of the power cord firmly into the receptacle on the rear panel of the Managed Switch. Plug the
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.
Power Notice:
In some areas, installing a surge suppression device may also help to protect your Managed Switch
from being damaged by unregulated surge or current to the Managed Switch or the power adapter.
