Rack-mounting by using front mounting brackets
Only the S5120-28C-EI, S5120-52C-EI, S5120-24P-EI, and S5120-48P-EI support installation by using
front mounting brackets.
To mount a switch into a 19-inch standard cabinet:
1. Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well
grounded.
2. Verify the grounding and stability of the rack.
3. Unpack the screws which are packed together with the front mounting brackets, and attach one
end of mounting brackets to the switch, as shown in
Figure 4 .
