General Site Installation Guidelines
The following precautions help you plan an acceptable operating environment for your SSR130 appliance
and avoid environmentally caused equipment failures:
•
Keep the area around the chassis free from dust.
•
Follow prescribed airflow guidelines to ensure that the cooling system functions properly and that
exhaust from other equipment does not blow into the intake vents of the appliance.
•
Follow the ESD procedures to avoid damaging equipment. Static discharge can cause components to
fail completely or intermittently over time.
•
Install the appliance in a secure area, so that only authorized personnel can access the appliance.
