2.1.3 Preparing for Setup
The UMG-2000 Series system was shipped with desk brackets, ear brackets, and mounting
screws, so it is possible to install the UMG-2000 Series 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.
2.1.4 Precautions
9 Review the electrical and general safety precautions.
9 Install the heaviest server components on the bottom of the rack first, and then work up
if you want to mount the UMG-2000 Series to a rack.
9 Use a power supply regulating uninterruptible (UPS) to protect the server from failure.
9 Allow the hot plug SATA drives and power supply units to cool before touching them.
9 Always keep the rack's front door and all panels and components on the servers
closed when not servicing to maintain proper cooling.
2.1.5 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.).
