Cuda 12000 IP Access Switch Installation Guide
Fan Tray 49
Fan Tray
The fan tray for the Cuda 12000, shown in Figure 1-14, contains three
hot-swappable fan modules encased within a 2U, 17.25”W x 3.5”H x
15.5”D aluminum chassis. Each fan module within the assembly contains
two 5-inch fans; these six fans provide cooling for a single chassis.
Three LEDs located on the front panel indicate the operational status of each
fan module within the assembly; green indicates the fan module is
operational; red indicates failure. In case of failure, the affected fan module
can be replaced without interruption to other fan modules within the unit.
Figure 1-14 Fan Tray
The fan tray draws in cooling air and pushes it up into the above system.
Intake vents on the front panel provide additional air flow. A sensor within
the unit monitors the temperature of the inlet air stream. If the temperature
of the air drawn into the unit is higher than desirable, all three LEDs on the
front of the unit illuminate red to indicate a fault condition. The front panel
is secured in place with eight captive thumbscrews.
The top, bottom, front, and rear of the system must remain unobstructed to
ensure adequate airflow and prevent overheating.
The fan tray must be mounted directly below each Cuda 12000. For
information on the proper placement of the fan tray within the rack, see
“System Placement in the Rack” on page 64.
