General Site Guidelines
The following precautions help you plan an acceptable operating environment for
your Services Router and avoid environmentally caused equipment failures:
For the cooling system to function properly, the airflow around the chassis
must be unrestricted. Allow at least 6 in. (15.2 cm) of clearance between the
front and back of the chassis and adjacent equipment. Ensure that there is
adequate circulation in the installation location.
Follow ESD procedures described in “Preventing Electrostatic Discharge
Damage” on page 205, to avoid damaging equipment. Static discharge can
cause components to fail completely or intermittently over time.
Install blank PIM panels in empty slots, to prevent any interruption or
reduction in the flow of air across internal components.
