■ AC Power Receptacle
For compatibility with electrical voltages in most areas of the world, the Managed Switch's power supply can automatically
adjust 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 and the other end
of the power cord into an electrical outlet and the power will be ready.
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.
Power Notice: 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
surge or current to the Switch or the power adapter.
■ DC Power Connector (SGS-5240-20S4C4XR)
The rear panel of the SGS-5240-20S4C4XR contains a DC power connector, which accepts DC power input voltage from
36V to 72V DC. Connect the power cable to the Managed Switch at the input terminal block.
