Electrostatic Discharge
Electrostatic discharge (ESD; static electricity) is caused by movement of people, furni-
ture, and equipment. ESD can damage circuit card components, alter information on mag-
netic media, and cause other equipment problems. The following steps are recommended
to minimize ESD potential in the data center:
• Provide a conductive path from raised floors to ground.
• Use floor panels with nonconducting cores.
• Maintain humidity levels within recommended control parameters.
• Use grounded anti-static work mats and wrist straps to work on equipment.
HVAC Requirements
Cooling and air-handling systems must have sufficient capacity to remove heat generated
by equipment and data center personnel. Raised-floor areas should have positive under-
floor air pressure to facilitate airflow. If conditions change within a data center (e.g., when
new equipment is added or existing equipment is rearranged), airflow checks should be
done to verify sufficient airflow.
