requirements for space and airflow, temperature, humidity, equipment room height, cleanliness, and
grounding.
Rack requirements
IMPORTANT:
T
o avoid affecting the server chassis, install power distribution units (PDUs)
with the outputs facing
backward
s. If you install PDUs with the outputs facing the inside of the server,
perform onsite survey
to make sure the cables won't affect the server rear.
The server is 4U high and has a depth of 781 mm (30.75 in). The rack for installing the server must
meet the following requirements:
•
A standard 19-inch rack.
•
Aclearance of more than 50 mm (1.97 in) between the rack front posts and the front rack door.
•
Aminimum of 1200 mm (47.24 in) in depth as a best practice. For installation limits for different
rack depth, see Table 2.

Guidelines for controlling corrosive gases
To control corrosive gases, follow these guidelines:
•
As a best practice, do not build the equipment room in a place with a high concentration of
corrosive gases.
•
Make sure the equipment room is not connected to sewer, sewage, vertical shaft, or septic tank
pipelines and keep it far away from these pipelines. The air inlet of the equipment room must be
away from such pollution sources.
•
Use environmentally friendly materials to decorate the equipment room. Avoid using organic
materials that contains harmful gases, such as sulfur or chlorine-containing insulation cottons,
rubber mats, sound-proof cottons, and avoid using plasterboards with high sulfur concentration.
•
Place fuel (diesel or gasoline) engines separately. Do not place them in the same equipment
room with the device. Make sure the exhausted air of the engines will not flow into the
equipment room or towards the air inlet of the air conditioners.
•
Place batteries separately. Do not place them in the same room with the device.
•
Employ a professional company to monitor and control corrosive gases in the equipment room
regularly.
Cleanliness requirements
Requirements of dust particle concentration vary by server model. For information about the
requirements, see the installation guide of the server.

10
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 Table 6. Make sure no zinc whiskers are in the
equipment room.
Table 6 Dust particle concentration limit in the equipment room
Particle diameter
Concentration limit
≥ 5 µm ≤ 29300 particles/m3
≥1 µm ≤832000 particles/m3
≥ 0.5 µm ≤3520000 particles/m3
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 "Powering on and powering off the server."
