Connect one end of the delivered AC power cable to the power socket of the RPS
power module and the other end to the socket of an external AC power supply.
2) Check whether the PWR LED on the front panel of the switch is ON. If yes, the
power is properly connected.
Caution:
Before powering on the switch, you should properly connect the grounding cable.
The DC power cable should be less than 3 meters long.
Only the recommended 12V-RPS DC power supply and power cables can be used.

3.2.3 Connecting Grounding Cable

Caution:
You should properly connect the switch grounding cable since it is crucial to the
lightning protection and electromagnetic shield (EMS) of your switch.
The power input end of the switch is connected with a noise filter, whose central ground
is directly connected to the chassis, forming the so-called chassis ground (commonly
known as PGND). This chassis ground must be securely connected to the earth so that
the faradism and leakage electricity can be safely released to the earth, enhancing the
EMS capability of the switch.
Ground the switch as follows:
When a grounding strip is available at the installation site, attach one end of the
yellow-green grounding cable of the switch to the grounding screw on the
grounding strip and fasten the captive nut. (Note that the fire main and lightning
rod of your building are not suitable for grounding the switch. The grounding cable
