Way2:
Use a standard RJ45 network cable to connect the network port of the PC and the console
port of the device, and configure and manage the device through the web.
4.6 Grounding
Grounding protects the device from lightning and interference. Therefore, you must ground
the device properly. You need to ground the device before it is powered on and disconnect
the grounding cable after the device is powered off.
There is a grounding screw(see ) on the Front panel of the device. The screw is for chassis
grounding. After crimping one end of the grounding cable to a cold pressed terminal, secure
the end to the grounding screw and firmly connect the other end to ground.
Note:
Cross-sectional area of the chassis grounding cable>2.5mm

; Grounding resistance<5
4.7 Power Terminal Block
There is a power terminal block on the Front panel of the switch. You need to connect the
power cable to the terminal block to provide power for the switch.
The device supports single (PWR1) and redundant (PWR1 and PWR2) power supply with a
5-pin 5.08mm-spacing plug-in terminal block. When the redundant power supply is used and
one power supply is faulty, the switch can continue operating properly, thereby improving
network reliability.
