5. Fix the front mounting brackets on the front square-holed brackets of the rack using the M6 screws
and cage nuts. Make sure that the switch is firmly fixed on the rack through the front mounting
brackets and slide rails.
NOTE:
Keep a distance of 1 U (44.45 mm/1.75 in) between two devices to ensure good heat dissipation.
Mounting the switch on a workbench
To mount the switch on a workbench, check the following:
• The workbench is sturdy and well grounded.
• The workbench is a well-ventilated environment. Keep at least 10 cm (3.94 in) clearance around the
switch for heat dissipation.
• No heavy object is placed on the switch.
• At least 15 mm (0.59 in) distance is provided between two devices when they are stacked one
above the other.
Grounding the switch
WARNING!
Correctly connecting the switch grounding cable is crucial to lightning protection and EMI protection.
The power input end of the switch has a noise filter, whose central ground is directly connected to the
chassis to form the chassis ground (commonly known as PGND). You must securely connect this chassis
ground to the earth so the faradism and leakage electricity can be safely released to the earth to
minimize EMI susceptibility of the switch.
You can ground the switch in one of the following ways, depending on the grounding conditions
available at the installation site:
• Grounding the switch with a grounding strip (recommended)
