Set the Switch on a smooth, level surface strong enough to support the weight of the Switch and the
connected cables. Make sure there is a power outlet nearby.
Cautions:
• Avoid stacking fanless Switches to prevent overheating.
• Ensure enough clearance around the Switch to allow air circulation for cooling.
• Do NOT remove the rubber feet as it provides space for air circulation.
2.4 Mounting the Switch on a Rack
The Switch can be mounted on an EIA standard size, 19-inch rack or in a wiring closet with other
equipment. Follow the steps below to mount your Switch on a standard EIA rack using a rack-mounting
kit.
Note: Make sure there is enough clearance between each equipment on the rack for air
circulation.
2.4.1 Installation Requirements
• Two mounting brackets.
• Eight M3 flat head screws and a #2 Philips screwdriver.
• Four M5 flat head screws and a #2 Philips screwdriver.
2.4.2 Precautions
• Make sure the rack will safely support the combined weight of all the equipment it contains. The
maximum weight a bracket can hold is 21.5 kg.
• Make sure the position of the Switch does not make the rack unstable or top-heavy. Take all
necessary precautions to anchor the rack securely before installing the unit.
