3.9 Environmental ConditionsLicense Requirements
This system is carrier class designed and complies with Considered equivalent to ATIS-0600010.01.2008 Class 2, Harsh – Protected Environment.
This system will properly work within Class 2 environments for equipment placed inside a space protected from direct outside weather and
environmental stresses by a closure and where the operating climate is between:
-40°C (-40°F) and 65°C (149°F)
5 and 85 RH% Relative Humidity
“These locations usually have either (a) active means of cooling using fans and/or heat exchangers, or (b) design features (cooling fins or airflow
pattern) within the closure or the equipment to effectively dissipate heat from active equipment.
Although these facilities do not have a preset specific temperature range as a target, their physical design features (e.g., cooling fins) and devices
(e.g., fans, heat exchangers) greatly aid heat dissipation and help moderate the thermal environment surrounding the electronic equipment.
The temperature conditions above are the expected extremes provided for equipment design purposes. Normal operating temperature and
humidity range experienced by the equipment in the closure is expected to be narrower. The operating temperature minimum of -40°C represents
a scenario where a cold start is required after an emergency, such as a power outage caused by an ice storm or downed electrical power lines.”
(GR-3108-CORE).
3.10 Electromagnetic Compatibility
This system is carrier class designed and suitable to work over extreme EM conditions. As such, it complies with the relevant recommendations for
this type of installation, as listed in the ETSI EN 300 386 recommendation.
