Before you begin to install the air filter unit, ensure that you have a Phillips (+) screwdriver, number 2
available.
WARNING: Ensure that you understand how to prevent ESD damage (see
Electrostatic Discharge Damage
NOTE: The air filter unit is installed on the cable management brackets. Before installing the air
filter unit, ensure that the cable management brackets are installed on front of the switch.
The air filter unit consists of three parts–the outer filter cover, the air filter, and the inner cage. The air
filter sits between the outer cover and the inner cage. The air filter unit is installed into the cable
management brackets, and are held tightly by captive screws.
Regularly inspect the air filter. A dirty air filter restricts airflow in the unit, producing a negative effect on
the ventilation of the chassis.
To install the air filter unit:
1. Wrap and fasten one end of an ESD wrist strap around your bare wrist, and connect the other end of
the strap to the ESD point on the switch.
