There is a power terminal block on the top panel of the device. You need to connect the
power wires to the terminal block to provide power to the device. The device supports
redundant power input with a 5-pin 5.08mm-spacing plug-in terminal block. When one power
input is faulty, the device can continue operating properly, thereby improving network
reliability.
