PLANET UMG-2000 - Manual (Page 7)

3.3 Preparing for Setup
The UMG-2000 / UMG-2200 system was shipped with desk brackets, ear brackets,
and mounting screws, so it is possible to install the UMG-2000 / UMG-2200 into
the mounted rack or on the desk brackets. Please read following sections in its
entirety before you begin the installation and follow the steps in the order given to
complete the installation process correctly.
3.4 Precautions
Review the electrical and general safety precautions.
Install the heaviest server components on the bottom of the rack first, and then
work up if you want to mount the UMG-2000 / UMG-2200 to a rack.
Use a power supply regulating uninterruptible (UPS) to protect the server from
failure.
Allow the hot plug SATA drives and power supply units to cool before touching
them.
Always keep the rack’s front door and all panels and components on the servers
closed when not servicing to maintain proper cooling.
3.5 Installation Consideration
Ambient Operating Temperature
If installed in a closed or multi-unit rack assembly, the ambient operating
temperature of the rack environment may be greater than the ambient temperature
of the room. Therefore, consideration should be given to installing the equipment
in an environment compatible with the manufacturer’s maximum rated ambient
temperature.
REDUCED AIRFLOW
Consideration should be given to the amount of airflow required for safe operation
maybe not compromised for the rack mounting.
Circuit Overloading
Consideration should be given to the connection of the equipment to the power
supply circuitry and the effect that any possible overloading of circuits might have
on over-current protection and power supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
Reliable Ground
A reliable ground must be maintained at all times. To ensure this, the rack
itself should be grounded. Particular attention should be given to power supply
connections other than the direct connections to the branch circuit (i.e. the use of
power strips, etc.).
