Switch Cooling Requirements

Wherever the switch is located, be sure to pay close attention to switch cooling
requirements. The location should be well ventilated and provide unrestricted
airflow at the front, back, and sides of the switch. If the airflow is insufficient, it may
cause the switch to overheat and possibly fail.

The following figure shows the cool air intake and the hot air exhaust airflow into
and from the switch.

Figure 11: Switch Cooling

Rack Cooling

When mounting the switch in an enclosed rack or cabinet, be sure to check the
following guidelines to prevent overheating:

◆

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 airflow.

◆

When possible, do not completely fill the rack or cabinet with equipment, allow
some unused space within the enclosure for better airflow.
