exposure to high temperatures in close proximity, and long term
reliability may be compromised.
Chassis Airflow Requirements
To ensure proper airflow through a switch, refer to the following recommendations when you
install the switch:
8800 series switches require a minimum of 1.5 inches (4 cm) around both the left and
•
right sides of the chassis from any cabinet wall or other obstruction for proper airflow.
Air temperature measured approximately 1 inch (2.5 cm) from the fan inlet should be less
•
than 104 °F (40 °C).
In the 8800 series switches, air moves through the power supplies independently of the
airflow through the modules, as shown in the following figure.

Electrostatic Discharge
Your system has to be protected from static electricity or electrostatic discharge (ESD). Take
the following measures to ensure optimum system performance:
