4.6 Power Terminal Block
There is a power terminal block on the top panel of the switch. You need to connect the
power cable to the terminal block to provide power for the switch. The switch supports both
single power supply and dual power supply for redundancy with a 5-pin 5.08mm-spacing
plug-in terminal block. When the dual power supply is used and one power input is faulty, the
switch can continue operating properly, thereby improving network reliability.
