Only the S5120-28C-PWR-EI and S5120-52C-PWR-EI support installation using front mounting
brackets together with rear mounting brackets.
Follow these steps to install a switch into a 19-inch standard cabinet:
Step1
Wear an ESD-preventive wrist strap and ensure a good skin contact and grounding.
Step2
Check the grounding and stability of the cabinet.
Step3
Take out the screws which are packed together with the front mounting brackets, and fix one end of
mounting brackets to the switch, as shown in Figure 3-5.
Step4
Take out the load-bearing screws (packed together with the rear mounting brackets) and place them in
a proper position on the sides of the switch, as shown in Figure 3-7.

There are three positions to mount a load-bearing screw on both sides of a switch. You should select a
proper position according to the actual requirements. The rear mounting brackets tightly contacted with
the load-bearing screws can support the switch.
Step5
Select a position to install the switch and fix the rear mounting brackets to the rear posts with screws
