systems: Airborne contaminants. Instrument Society of America, Research Triangle
Park, NC, 1985.
2.
The derivation of the equivalence between the rate of copper corrosion product
thickness growth in Å/month and the rate of weight gain assumes that Cu
2
S
and Cu
2
O grow in equal proportions.
3. The derivation of the equivalence between the rate of silver corrosion product
thickness growth in Å/month and the rate of weight gain assumes that Ag
2
S is
the only corrosion product.
4. The deliquescent relative humidity of particulate contamination is the relative
humidity at which the dust absorbs enough water to become wet and promote
corrosion, ion migration, or both.
5. Surface debris is randomly collected from 10 areas of the data center on a 1.5
cm diameter disk of sticky, electrically conductive tape on a metal stub. If
examination of the sticky tape in a scanning electron microscope reveals no zinc
whiskers, the data center is considered free of zinc whiskers.
Planning for safety
You must consider various safety issues when you plan your storage system
location.
The following list identifies some of the safety issues you must consider:
v Fire suppression
v Service navigation
Providing a fire-suppression system
Set up an environment that supports the temperature, cooling, and operating
requirements of your storage system. You are responsible for providing a fire
suppression system for your storage system.
About this task
IBM designs and manufactures equipment to internal and external standards that
require certain environments for reliable operation. Because IBM does not test any
equipment for compatibility with fire-suppression systems, IBM does not make
compatibility claims of any kind. IBM does not provide recommendations on
fire-suppression systems.
Procedure
1.
Consult your insurance underwriter, local fire marshal, or local building
inspector about selecting a fire-suppression system that provides the correct
level of coverage and protection.
2. Set up an environment that supports the temperature and cooling requirements
for your storage system as described in the environmental temperature
requirements-planning area.
Providing service navigation equipment
You are responsible for providing appropriate service equipment for your storage
system.
The DS8882F model 983 requires two service representatives to install at your site
because of the weight of the components. You must provide the installation safety
equipment based on the position of the components in your frame.
