Mounting in the network box
NO TICE
l
Do not use an enclosed network box and ensure that the air intake and exhaust vents are
not blocked to ensure proper heat dissipation of the ONU.
l
If the network box is installed indoors or in a corridor that is free from rain, the network
box must meet the requirements of IP31 protection. ("IP" is short for international
protection. The first number indicates a class for preventing the solid particle from
entering the device and the second number indicates a class for preventing water from
entering the network box. "3" means that solid particles with diameters equal to or larger
than 2.5 mm can be prevented from entering the box. "1" means that the drips fallen
vertically cannot damage the device.)
l
If the network box is installed outdoors or in a corridor that is exposed to rain, the network
box must meet the requirements of IP55 protection. ("5" means that the network box
cannot completely prevent dust from entering, but the amount of dust that enters the
network box does not damage the device. "5" means that the water sprayed from different
directions to the network box does not damage the device.)
l
The method for installing the ONU in a non-Huawei network box depends on the network
box specifications. When the ONU is installed in a non-Huawei network box, the
preceding heat dissipation space rules must be observed.
