Install the Switch in a site free from strong electromagnetic field 
generators (such as motors), vibration, dust, and direct exposure to 
sunlight. 
Leave at least 10cm of space to the front and rear of the Switch for 
ventilation. 
Install the Switch on a sturdy, level surface that can support its 
weight, or in an EIA standard-size equipment rack.  For information 
on rack installation, see the next section, Rack Mounting. 
When installing the Switch on a level surface, attach the rubber 
pads (feet) to the bottom.  The rubber feet cushion the switch and 
helps protect the case from scratches.

side), and secure them with the provided screws.
