CAUTION
S3600 series switches can be installed with two power modules for hot spare, so that
switching to another power supply (without power interruption) can be realized in the case of
one power supply failure.
2.2.5 Ground Connection
The power input terminal of switch is connected with noise filter of which the central place is
directly connected with the chassis, which is called chassis grounding wire (namely protective
grounding wire). The chassis grounding wire must be connected properly, so that induced
current and leakage current can flow into the ground safely and the ability of
anti-electromagnetic interference of the complete machine can be enhanced.
Correct grounding mode:
Connect one end of the green-yellow protective grounding cable of switch to the grounding
terminal of switch, and the other end to the wiring terminal on the grounding bar of machine
room.
NOTE
The grounding wire of Ethernet switches must be connected and grounded with switch room.
Grounding connection with fire mains and lightning rod is not correct.

(3): Grounding terminal of machine room
CAUTION
Correct connection of switch grounding terminal is an important guarantee for lightning
protection and anti-interference of switches, so users must connect grounding wire correctly.
The position of grounding wire connection and machine room grounding in the figure are for
reference only. Please take consideration of the actual conditions of equipment.
