Environmental Requirements
Tekelec products are designed for environments that have temperature and humidity controls.
Temperature and humidity controls must be activated as quickly as possible for equipment to operate
at an optimum level.
When temperature and humidity controls fail, the equipment has been tested to operate within the
following ranges:
• Temperature
• 5˚ C to 40˚ C (41˚ F to 104˚ F) for normal operation
• -5˚ C to 50˚ C (23˚ F to 122˚ F) for no more than 96 hours in duration and at elevations less than
1800 meters
• -5˚ C to 50˚ C (23˚ F to 122˚ F) for storing the product
• Humidity
• 5% to 85% non-condensing for normal operation
• 5% to 90% non-condensing (but not to exceed 0.024 kilograms of water per kilogram of dry air)
for no more than 96 hours in duration and at elevations less than 1800 meters
Tekelec products are tested to operate at an elevations within the following range:
• Minimum: 60 meters below sea level at ambient temperature of 30˚ C (86˚ F)
• Maximum: 4000 meters above sea level at ambient temperature of 40˚ C (104˚ F)
HVAC Requirements
Tekelec products are designed to bring cool air in from the bottom front and exit heated air out the
top rear of the installed equipment.
The required HVAC (Heating, Ventilation, and Air Conditioning) capacity depends on the installed
equipment. To calculate needed HVAC capacity, determine the total wattage of the installed equipment
and use the following formula:
BTUs/hr. = watts x 3.413
The amount of power required by frame components is found at:
.
The E5-APP-B card must be installed in a fully populated EAGLE shelf with a fan tray and air
management cards, if necessary.
Lighting
Adequate lighting should be provided in the room where the equipment is to be located. Lighting
fixtures must be far enough from the equipment and cables to prevent heat damage and to allow safe
access to equipment and cables.
