Desktop Mount the ASA
You can mount the ASA on a desktop by placing it on a desk in a horizontal position. Make sure there are no blockages or obstructions within one inch of the top of the ASA or within .5 inch of the sides and back, so that nothing interferes with cooling. Do not remove the rubber feet included with the ASA. They are also needed for proper cooling.

![]() Caution |
Do not stack the ASA chassis on top of another ASA chassis. If you stack the units, they will overheat, which causes the units to power cycle. |
