The temperature, dew point and relative humidity in the server room should meet the
requirements for operating the server. For specified requirements, see the detailed
description in the product documentations.

Organisms
Plants and animals are not allowed in the server room. Take strict precautions against
damage by rats and ants.
To meet these requirements, take the following measures in the server room:
Ensure safety if there are humidification devices in the server room.
All the structures and construction gaps of doors, windows, walls, ground (floors)
must be sealed.
If there are water supply and drainage pipes in the server room, anti-leakage and
anti-condensation measures should be taken.
If there is water equipment in the main server room, measures to prevent water
overflow and leakage should be taken.
Block cable holes and antenna holes.
Clean and sterilize the server room periodically.

Corrosive Airborne Contaminants
Generally, a small amount of common corrosive gas pollutants exist in indoor and
outdoor atmospheric environments. Chemical reactions may occur due to long-term
contact between these mixed corrosive gas pollutants or pollutants of one single
corrosive gas and other environmental factors (such as temperature or relative
humidity), which may pose a risk of IT equipment failure from corrosion and damage
circuit boards of IT equipment and system component units with weak oxidation
resistance. This article specifies the limitation on corrosive airborne contaminants with
an aim to avoid such risks.
The concentration level of corrosive airborne contaminants in a data center shall meet
the requirements listed in the white paper entitled Gaseous and Particulate
Contamination Guidelines for Data Centers published in 2011 by American Society of
Heating Refrigerating and Air-conditioning Engineers (ASHRAE) Technical Committee
(TC) 9.9. According to the Guidelines, corrosive airborne contaminants in a data center
shall meet the following requirements:
Copper coupon corrosion rate less than 300 Å/month per ANSI/ISA-71.04-2013
severity level G1
Silver corrosion rate less than 200 Å/month per ANSI/ISA-71.04-2013 severity level
G1
According to ANSI/ISA-71.04-2013 Environmental Conditions for Process
Measurement and Control Systems: Airborne Contaminants, the gaseous
