RG-S2600G-I Series Switch Hardware Installation and Reference Guide
EMC Grounding
The grounding required for EMC design includes shielding ground, filter ground, noise and interference suppression, and
level reference. All the above constitute the comprehensive grounding requirements. The grounding resistance should be
less than 1 ohm. The RG-S2600G-I backplane is reserved with one grounding pole, as shown in 2-1.

Lightning Resistance Considerations
When the AC power cable is imported outdoors and directly connected to the power port of the switch, lightning line bank
should be adopted to prevent the switch from being hit by lightning shocks. The lightning line bank can be fixed on the
cabinet, work station, or the equipment room's wall through line buckles and screws. In applications, the AC first enters
the lightning line bank and then the switch.
The lightning line banks are not provided and should be purchased by users as required.
For the usage of lightning line banks, refer to their related manuals.
EMI Consideration
Various interference sources, from either outside or inside the equipment or application system, affect the system in the
conductive ways such as capacitive coupling, inductive coupling, and electromagnetic radiation.
There are two types of electromagnetic interferences: radiated interference and conducted interference, depending on the
type of the transmission path.
When the energy, often RF energy, from a component arrives at a sensitive component via the space, the energy is
known as radiated interference. The interference source can be either a part of the interfered system or a completely
electrically isolated unit. Conducted interference results from the electromagnetic wire or signal cable connection between
