Power Notice:
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.
In some area, 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
The rear panel of the SGSW-24040R contains a power switch and a DC power connector, which accepts DC power input
voltage from -30V to -60V DC. Connect the power cable to the Managed Switch at the input terminal block. The size of the
two screws in the terminal block is M3.5.
