Installation Precautions in a Harsh Environment
Definition of harsh environment
Within 3.7 km (12139 ft ) of an ocean or a salt water lake
When outdoor equipment or cabinets are installed in a harsh environment, ensure that the following requirements
are met:
Antenna installation requirements
 If glue dispensing is not done on the rivets or screws of the center plate and reflective surface of an antenna
before delivery, apply matching outdoor adhesive to them.
 Apply thread adhesive to screws used for installing antennas. This can prevent the screws from becoming
loose and improve corrosion resistance.
 After you finish installing screws, spread oil or spray paint on the surface of the screws.
 In areas with many birds, install protective covers to prevent birds' droppings from corroding antennas.
Branching unit installation requirements
 Spread oil or spray paint onto the clamps of flexible/elliptical waveguides.
 After you finish installing exposed screws, spread oil or spray paint on the surface of the screws.
 In areas with many birds, install protective covers to prevent birds' droppings from corroding branching units.
IDU cabinet installation requirements
 Outdoor cabinets must be equipped with heat exchangers or air conditioners.
 The air exhaust vent of an air conditioner must not face equipment.
 Equipment rooms must be airtight. Equipment rooms and dust filters of equipment must be cleaned regularly.
 Equipment room doors must not face the wind.
 Install filler panels in vacant slots of the IDU to prevent dust accumulation in the slots and corrosion caused by
salt fog.
