Grounding The Switch With A Grounding Strip - HP V1910 Series Getting Started Manual

CAUTION:
 Correctly connecting the switch grounding cable is crucial to the lightning protection and EMI protection.
The power interface and grounding terminals in this section are for illustration only.

The power input end of the switch has a noise filter, whose central ground is directly connected to the
chassis to form the chassis ground. You must securely connect this chassis ground to the earth so that the
faradism and leakage electricity can be safely released to the earth to minimize EMI susceptibility of the
switch.

Follow these steps to connect the grounding cable:
Remove the grounding screw from the rear panel of the switch chassis.
Step1
