Introduction to Guide Rail
Guide rails are optional parts. Check Table 3-1 to see whether you need to order them or not.

(1) Slotted hole 1: Used to fix the guide rail to the rear post. You can adjust the screw hole position
according to the position of the switch.
(2) Cooling hole: Used for heat dissipation between switch and cabinet
(3) Slotted hole 2: Used to fix the guide rail to the front bracket
Guide rails purchased from H3C apply only to standard cabinets 1,000 mm (39.37 in.) deep. Use other
supports to substitute for guide rails in the case of other cabinet depths.
Use Front Mounting Brackets to Install a Switch
Only the S5120-28C-EI, S5120-52C-EI, S5120-24P-EI, and S5120-48P-EI support installation using
front mounting brackets.
Follow these steps to mount 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.
