Zorluk: ZorSafety Procedures and Environmental Controls

Following a prolonged cold wave, a data center HVAC humidifier unit malfunctions, causing relative humidity inside the server room to drop to 14%. Shortly thereafter, technicians servicing hot-swappable blade servers report frequent static discharges, and two drive array controllers experience failure from electrostatic discharge (ESD). While waiting for HVAC replacement parts, which immediate operational measure should the lead technician implement to mitigate static charge accumulation?

  1. Deploy temporary commercial humidification units to elevate and maintain relative humidity levels between 40% and 55%Cevap
  2. B
    Instruct technicians to attach ESD wrist strap alligator clips directly to the ground pin of active 120V electrical wall outlets
  3. C
    Shut down the primary HVAC air circulation blowers completely to eliminate static generation caused by airflow friction
  4. D
    Apply liquid aerosol anti-static spray directly onto server chassis intake vents and rack cabling

Cevap

Deploying temporary commercial humidification units to raise and maintain relative humidity levels between 40% and 55% is the correct procedure.
Low relative humidity dry air significantly accelerates electrostatic charge buildup. Raising and holding relative humidity between 40% and 55% using portable commercial humidifiers allows moisture in the air to naturally dissipate static electricity charges before ESD damages sensitive silicon components.

Adım Adım Çözüm

1
Analyze the environmental root cause of static electricity accumulation.
Extremely low relative humidity (14%) causes dry air, which promotes high electrostatic charge buildup on physical surfaces and personnel.
Water vapor in humid air acts as a natural conductor to bleed off static charges safely.
2
Identify environmental control standard thresholds for IT data centers.
Standard environmental guidelines specify maintaining relative humidity between 40% and 55% to prevent ESD while avoiding condensation.
Humidity below 40% drastically increases ESD risks, whereas humidity above 60% risks condensation and corrosion.
3
Select the appropriate temporary remediation measure.
Deploying commercial humidifiers restores the humidity to the 40%-55% target range without creating electrical short-circuit or thermal hazards.
This directly remediates the environmental cause of ESD while maintaining safe server room operating parameters.
