Understanding Server Cooling Zones
Switch Chassis Cooling Zones
The switch chassis has seven cooling zones. Six of the cooling zones contain a horizontal row
of six fan modules each. Each of these zones pushes air through a single switch unit from the
front of the server and exhausts it at the rear of the server. In the other cooling zone, four fan
modules push air through the power supplies and exhaust it through the chimney to the SPs and
directly out the rear of the chassis.
