Fan Tray Module

The fan tray module is an important part of the switch air cooling system. A fan tray
module must be installed in the switch at all times. If a fan should fail, the whole fan
tray module must be replaced as soon as possible.
You must install the fan tray module in the switch that matches the airflow
direction of the installed power supply units. The available fan tray modules are
listed below:

Caution:
installed into its chassis. All installed modules must have a matching airflow
direction. That is, all modules must have a front-to-back (F2B) airflow direction, or
all modules must have a back-to-front (B2F) airflow direction. The airflow direction
of PSUs and fan trays is indicated by labels on the modules.
The removable fan tray, located in the rear of the switch, includes four fixed fans
and supports fan speed control. The fan speed is dynamically controlled as a
function of temperature: the higher the internal temperature, the faster the speed
of the fans. The fan tray module does not include LED indicators.
Make sure that enough cool air can flow into the enclosure for the equipment it
contains.
Check that the rack or cabinet allows the hot air to exit the enclosure (normally
from the top) without circulating back into equipment.
If the enclosure has sides or doors with ventilation holes, make sure they are
not blocked by cables or other obstructions.
Route cables within the rack or cabinet to maximize the air flow.
When possible, do not completely fill the rack or cabinet with equipment, allow
some unused space within the enclosure for better air flow.
