4.6 Power Terminal Block
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 for the device. The device supports redundant power
supply with 5-pin 5.08mm-spacing plug-in terminal block. When the redundant power supply is
used and one power input is faulty, the device can continue operating properly, thereby improving
network reliability.
