Chapter 2 Preparing for Installation
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.
Caution Do not permit third party equipment to impede airflow around the mobility services engine or to increase
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
installation of information technology equipment by licensed electricians. This equipment is designed
to operate in installations covered by NFPA 70, 1999 Edition (National Electric Code) and NFPA-75,
1992 (code for Protection of Electronic Computer/Data Processing Equipment). For electrical power
ratings on options, refer to the product rating label or the user documentation supplied with that option.
Caution Protect the mobility services engine from power fluctuations and temporary interruptions with a
regulating uninterruptible power supply (UPS). This device protects the hardware from damage caused
by power surges and voltage spikes and keeps the system in operation during a power failure.
Mobility Services Engine Power Supply
The mobility services engine has one power supply.
Caution Verify that the external power source connected to the mobility services engine matches the type of
power source indicated on the electrical ratings label. If you are not sure of the type of power source
required, consult your Cisco authorized reseller or local power company.
Batteries
The mobility services engine might include a real-time clock battery or coin cell battery that contains
perchlorate. If so, it might require special handling when recycled or disposed of in California.
Refer to the following link for disposal information.

Caution Do not dispose of batteries with general household waste. Recycle them using the public collection
system.
