A data center manager notices increased dust accumulation inside server chassis, leading to overheating concerns. Which environmental control should be implemented FIRST to address this issue?
- AIncrease the humidity level in the room
- BAdd additional UPS units to the room
- CInstall high-efficiency particulate air (HEPA) filtration
- DLower the ambient temperature setpoint
Show answer & explanationAnswer & explanation
Correct answer: C. Install high-efficiency particulate air (HEPA) filtration
HEPA (or high-efficiency particulate) air filtration removes dust and particulates from the air supply before it circulates through the data center, directly addressing dust accumulation inside equipment. Adjusting humidity, temperature, or adding UPS units does not solve a particulate contamination problem.
Why the other options are wrong
- A. Humidity affects ESD/condensation risk, not dust accumulation.
- B. UPS units relate to power backup, not air quality.
- D. Lowering temperature does not address the source of dust contamination.
Particulate/Air Filtration Control
Environmental control using filters (e.g., HEPA) to remove dust and particulates from data center air to prevent equipment contamination.
- Dust buildup can cause overheating and component failure
- Filtration is part of broader HVAC environmental controls
- Should be paired with proper humidity and temperature control
Memory trick: Filter the air to save the gear.
