Huawei SmartAX MA5612 - Maintenance Tools

1. When you open the cabinet door, prevent rain and snow from falling into the inner surface
of the device (including the front panel of the service board), from falling into cables, or
from falling into apertures.
2. Do not open the cabinet door in heavy dust. If the dust enters the cabinet, the service life
of the components is affected seriously.
3. It is recommended that you open the cabinet door to maintain the device when the
temperature is in the range from -5°C to +35°C. In this way, the device can be protected
from dew condensation or impact of extreme temperatures.
4. Exercise caution when opening the cabinet door in the case of strong wind. A strong wind
may cause the cabinet door to be opened or closed fiercely. This is dangerous to the
maintenance engineer and may damage the device. Use a door brake to fix the cabinet door
in a specified position.
