Environmental Monitoring

Correct Answer: Check if the air conditioning system is working

The first step should be to check if the air conditioning system is working to identify the root cause of the temperature increase. Immediate server shutdown should be performed only if there is a risk of equipment damage. Always consult with the IT department before opening windows or doors, as it may introduce contaminants. Additional fans can be considered but should be done after troubleshooting the air conditioning system.

Correct Answer: Use a dehumidifier to maintain appropriate humidity levels

Utilizing a dehumidifier specifically helps to control humidity levels, whereas other options such as opening windows can introduce contaminants. The other options should only be considered if a dehumidifier is not available or shows no improvement.

Correct Answer: Relative humidity

Relative humidity is the crucial environmental factor to monitor in a data center to prevent electrostatic discharge (ESD) damage. Explanation: Relative humidity plays a significant role in controlling static electricity. When the air is too dry (low humidity), static charges can build up more easily on surfaces and people, increasing the risk of ESD. Maintaining an appropriate level of relative humidity (typically between 40-60%) helps dissipate static charges and reduces the likelihood of ESD events. Why other answers are incorrect: Barometric pressure does not directly affect ESD. While it can influence other aspects of data center operation, it has minimal impact on static electricity buildup. Carbon dioxide levels are important for air quality and human health but do not significantly influence ESD risk. Ambient light intensity has no bearing on static electricity or ESD prevention. While proper lighting is important for data center operations, it does not affect electrostatic charges.
