switch properly. You need to ground the switch before it is powered on and disconnect the
grounding cable after the switch is powered off.
The switch provides a grounding screw on the rear panel for chassis grounding. After crimping one
end of the grounding cable to a cold pressed terminal, secure the end to the grounding screw and
connect the other end to the earth firmly.

4.5 Power Terminal Block
There is a power terminal block on the rear panel of the device. You need to connect the power
wires to the terminal block to provide power for the device. The device supports both single and
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.
