The recommended cross-sectional area of a live wire/neutral wire (L/N) power cable for decoupling is 1.25 mm².
The cross-sectional area of a PE ground cable must be greater than or equal to 16 mm².
If there is no space for placing 5-10 m power cables in the cabinet for decoupling, install a hollow-core surge protection
decoupling inductor with an inductance of 5-10 µH on both the L and N wires. The decoupling inductors need to be
purchased separately.

5 Installing the Chassis
Scenario 1: Desk Mounting
Scenario 2: Wall Mounting
Do not stack fanless switches on top of or closely next to each other.
S5720I-SI series switches provide a security slot ( ) near the panel on a side of the chassis. You can install a
security lock (separately purchased) in this slot to protect the switch against theft.

Step 4
Before drilling holes in a wall, make sure there are no power cables in the wall to avoid electric shock.
The port-side panel must face down to protect the ports from water damage.
Ensure that there are no flammable or explosive materials near the switch and no obstructions within 100 mm
around the switch.
The expansion bolts need to be purchased separately.
