Requirements for the data center equipment room
The concentration of dust participles in the equipment room must meet the ISO 8 cleanroom
standard defined by ISO 14644-1, as described in
. Make sure no zinc whiskers are in the
equipment room.

Requirements for the non-data center equipment room
The concentration of dust participles (particle diameter
≥ 0.5 µm) must meet the requirement of the
GB 50174-2017 standard, which is less than 17600000 particles/m3.
Guidelines for controlling cleanliness
To maintain cleanliness in the equipment room, follow these guidelines:
•
Keep the equipment room away from pollution sources and do not smoke or eat in the
equipment room.
•
Use double-layer glass in windows and seal doors and windows with dust-proof rubber strips.
•
Use dustproof materials for floors, walls, and ceilings and use matt coating that does not
produce powders.
•
Keep the equipment room clean and clean the air filters of the rack regularly.
•
Wear ESD clothing and shoe covers before entering the equipment room. Keep the ESD
clothing and shoe covers clean and replace them frequently.
Grounding requirements
Correctly connecting the server grounding cable is crucial to lightning protection, anti-interference,
and ESD prevention. The server can be grounded through the grounding wire of the power supply
system and no external grounding cable is required.
Storage requirements
Follow these guidelines to store storage media:
•
As a best practice, do not store an HDD for 6 months or more without powering on and using it.
•
As a best practice, do not store an SSD, M.2 SSD, or SD card for 3 months or more without
powering on and using it. Long unused time increases data loss risks.
•
To store the server chassis, or an HDD, SSD, M.2 SSD, or SD card for 3 months or more, power
on it every 3 months and run it for a minimum of 2 hours each time. For information about
powering on and powering off the server, see "
