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-2910C-XS-P back plane is reserved with one grounding pole, as shown in 0.

Lightning Resistance
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.
Precaution for Fiber Connections
Before you connect the fibers, check that the optical connector type and fiber type match the optical interface type used. In
addition, pay attention to the Tx and Rx directions of the fiber. The Tx end of this equipment should be connected to the
Rx end of the peer equipment, and the Rx end of this equipment to the Tx end of the peer equipment.
