Choosing a Physical Location for the Mobility Services Engine
Temperature Requirements
To ensure continued safe and reliable equipment operation, install or position the system in a well
ventilated, climate-controlled environment.
Ensure that the ambient operating temperature remains between 50 to 95°F (10 to 35°C), taking into
account the elevated temperatures that occur when equipment is installed in a rack.
Do not permit third party equipment to impede airflow around the mobility services engine or to increase
Caution
the internal rack temperature beyond the allowable limits. Do not exceed the manufacturer's temporal
multi-resolution analysis (TMRA) limits.
Power Requirements
Installation of this equipment must comply with local and regional electrical regulations governing the
