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.
