When the equipment is installed in a network cabinet, the temperature at the air intake vent of the network cabinet must be within the range of -40°C to 55°C (-40°F to 131°F). For details on the requirements for network cabinets, see the Installation Guide.
When the equipment is installed in an APM30 outdoor cabinet, the temperature at the air intake vent of the outdoor cabinet must be within the range of -40°C to 55°C (-40°F to 131°F). For details on the requirements for outdoor cabinets, see the Installation Guide.
If the equipment is installed in a cabinet, the impact of radiation can be ignored. If the equipment is installed outdoors, proper protection must be provided for the equipment against radiation.

To improve product application reliability, it is recommended that a dedicated precision air conditioner be installed in an equipment room and the temperature and relative humidity be controlled within the following ranges:
http://support.huawei.com/huaweiconnect/public_sys-resources/icon-note.gif NOTE: Do not install the air conditioner above the equipment and ensure that the air exhaust vent of the air conditioner does not face the equipment. Keep the air conditioner away from a window as far as possible to ensure that no moisture from the window is blown towards the equipment through the air conditioner.Altitude ≤ 4000 m (13123.2 ft)
(When the altitude is lower than 1800 m (5905.44 ft), the equipment operates normally. When the altitude is within the range from 1800 m to 4000 m (from 3280.8 ft to 13123.2 ft), the actual equipment operating temperature decreases by 1ºC (1.8ºF) for every 220 m (721.78 ft) increase in altitude.)Temperature change rate ≤ 0.5ºC/min Wind speed ≤ 5 m/s Solar radiation ≤ 700 W/m2 Heat radiation ≤ 600 W/m2 Biological environment requirements
