Attach the rubber feet to each corner on the bottom of the Switch. These rubber feet help protect the
Switch from shock or vibration and ensure space between devices when stacking.
Note: Rubber feet will be attached to the GS1920-8HPv2 by default. To make sure of air
circulation, do NOT remove them.

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.
5
Make sure there is at least 40 mm of clearance around and from the surface to the bottom of the Switch
to allow air circulation and the attachment of cables and the power cord.
Note: Make sure that you meet the requirements of clearance when you use the Switch for
stacking. It’s recommended to only use the Switch with Fans in a stack. See Table 1 on
page 20 to see whether your Switch has fans.
