Rack Cooling

The top-of-rack switch is a high-performance, high-density unit that generates a
substantial amount of heat. When mounted in a rack with other equipment, it is
important that the switch has the same airflow direction to avoid "hot loops" in the
data center aisles. Hot loops increase cooling requirements since warm air is drawn
into rack devices instead of cool air.
Most rack-mounted blade servers draw cool air from the front and expel hot air at
the rear. The top-of-rack switch includes power supply units and a fan tray module
that have a front-to-back (F2B) airflow direction that maintains cool aisles in the
data center.
