the requirements for operating the server. For specified requirements, see the
detailed description in the product documentations.
2.
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
