3.2 Reviewing Rack Compatibility
Verify that your rack is compatible with the slide-rail and cable management arm
(CMA) options. The optional slide-rails are compatible with a wide range of equipment
racks that meet the standards listed in.

rear mounting planes
Minimum 610 mm and maximum 915 mm
(24 inches to 36 inches).
Clearance depth in front of
front mounting plane
Distance to front cabinet door is at least 25.4 mm
(1 inch).
Clearance depth behind front
mounting plane
Distance to rear cabinet door is at least 900 mm (35.5 inches)
with the cable management arm, or 770 mm (30.4 inches)
without the cable management arm.
Clearance width between front
and rear mounting planes
Distance between structural supports and cable troughs is at
least 456 mm (18 inches).

3.3 Before You Begin
Before installing Oracle Exalytics In-Memory Machine into a rack, read the following
cautions and important notes:
•
Always load equipment into a rack from the bottom up, so that the rack will not
become top-heavy and tip over. Deploy your rack's anti-tip bar to prevent the rack
from tipping during equipment installation.
•
If the Oracle Exalytics In-Memory Machine is installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment might be
greater than room ambient temperature. Therefore, consideration should be given
to installing the equipment in an environment compatible with the maximum
ambient temperature (Tma) specified for the Oracle Exalytics In-Memory Machine.
•
Installation of the equipment in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised.
•
Mounting of the equipment in the rack should be such that a hazardous condition
is not achieved due to uneven mechanical loading.
•
Consideration should be given to the connection of the equipment to the supply
circuit and the effect that overloading of the circuits might have on over-current
protection and supply wiring. Appropriate consideration of equipment nameplate
power ratings should be used when addressing this concern.
