Site Environment
The OS-10 system can be mounted in a rack or on a wall. The location of the chassis and layout of your equip-
ment rack or wiring room are extremely important for proper system operation. Equipment that is too close
together, ventilation that is inadequate, and panels that are inaccessible can make system maintenance difficult
or cause system malfunctions and possible shutdowns.

The following precautions help you plan an acceptable operating environment for your OS-10 system and
avoid environmentally caused equipment failures:
avoid environmentally caused equipment failures:
•
Ensure that the room in which you operate your system has adequate air circulation. Electrical equipment
generates heat. Ambient air temperature might not be able to cool equipment to acceptable operating tem-
peratures without adequate circulation.

•
Always follow the proper ESD-prevention procedures described in §3.2 (Electrostatic Discharge Damage)
to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent equip-
ment failure.

•
Ensure that the chassis cover and all expansion slot covers are secure. The chassis is designed to allow cool-
ing air to flow effectively inside it. An open chassis allows air leaks, which might interrupt the flow of cool-
ing air from internal components.

Maximum recommended operating temperature – The maximum recommended operating temperature for
the OS-10 is 50°C (122°F). Determine a suitable operating environment based on this recommendation.

Elevated operating ambient temperature – If the unit is installed in a closed or multiunit rack assembly, the
operating temperature of the rack environment may be greater than the ambient temperature of the room.
Keep this in mind when you install the unit.

Reduced airflow – Install the OS-10 system chassis in the rack so that the amount of airflow required for safe
operation of the equipment is not compromised.

Mechanical load – Mount the OS-10 system chassis in the rack to avoid a potentially hazardous condition due
to uneven mechanical loading.

Circuit overload – When you connect the OS-10 system chassis to the supply circuit, consider the effect that
overloading of the circuits might have on over-current protection and supply wiring.

Planning Your Site
Site Requirements
To install your OS-10 equipment successfully, you should plan your site carefully. The site planning process
has three major areas for consideration to ensure that your physical installation meets the requirements for a
safe and successful installation:
