FAQ About Data Centers
Electrical Grounding
Is you floor grounded? If there is
electrical build-up or a grounding
problem on top of the floor, it can
cause major problems and
shut
down your system. The access floor panel must be positively
grounded to the understructure, providing for
less than 10 ohm
resistance from the metal top
of the panel to the bottom of the pedestal base
where the building's grounding
system is
attached. ASM is the only manufacturer to comprehensively
address this problem by incorporating a solid
brass
Positive Grounding Device (PGD) in every
panel as standard equipment. A small detail
solves a critical
problem. Make sure your panels
are grounded - PGD is standard with all ASM
panels that have an ESD finish. Zinc Whiskering Zinc whiskering happens when certain
electro-plated zinc based coatings are used
under the access floor.
The zinc in the coating
gradually forms zinc particles. These particles
can become airborne and cause your systems
to short circuit. There is a wealth of articles and
information available regarding this growing
phenomenon in the data center environment.
Stringers
ASM's high strength stringers deliver
unprecedented strength because of their unique
solid tube design.
ASM's tube configuration is
structurally superior to the standard U-shaped
roll formed stringers offered by
other access
floor companies in North America. Be sure to
specify the tube type stringer with the black vinyl
strip, for ultimate strength and quiet durabilty. How are ASM panels protected from
rust and corrosion? Corrosion Resistant Process
The ASM FS and S-Series panels are first fully
immersed in a corrosion resistant bath of
phosphate to
protect inner and outer surfaces
prior to applying the epoxy powder coat finish.
Each panel is hand
polished to a bright
clean luster. How do you ensure panel flatness?
ASM is the only manufacturer to stamp the hollow
panel one additional time after welding to ensure
the
panel is flat after potential distortion during
the welding process. Is it the industry standard to advertise
CISCA performance results only?
No - you must check tables and charts and make
certain it is clearly noted that results represented
are
according to CISCA test procedures. If there
is no mention of CISCA, you can assume they
are not by
CISCA standards. Seismic
What special considerations must be
taken into account for data centers in
geographic zones prone to seismic
activity? Raised floors enhanced for seismically active
regions must have heavy cast undersides and
the sturdiest
support pedestals in the industry.
When architechural components, electrical and
mechanical equipment
mounted in your
computer room must withstand the displacing
forces that arise from seismic activity,
choose
ASM's new Atlas Pedestal Systems.
ASM's Atlas Pedestals have the highest support
rating. The pedestal head is threaded into the
pedestal
base, eliminating the fear of panels
shifting or lifting during sudden movements.
This allows equipment to
be bolted directly into
the raised floor, and eliminates the need for
additional elaborate bracing under the
floor.
Unparalleled strength and simplicity, designed
for seismic lateral loading without the need for
diagonal bracing. Easy to install.
With new high-density equipment
in computer rooms, such as blade
servers, do
you question your
computer room's ability to handle
such heat loads?
ASM's Air Flow Series allows for maximum
movement of cool air from the plenum
throughout the
workspace,
keeping equipment
protected from overheating. If you need a
concentrated volume of cool
air, choose
ASM's
air flow panel.Is it possible to have a smooth
transition from solid panel to
perforated panel? ASM's adjustable height system solves long
running industry problems of leveling the
perforated panel with
the adjacent solid panel -
a smooth transition from perforated to solid
panel is now possible. Can a perforated panel provide
structural integrity? Yes - ASM's AF200 panel can. The AF200's
exterior surfaces sandwich an interior structural
grate, providing
strength unparalleled by industry
counterparts.
