compromise the reliability and even service life of the device. The temperature/humidity requirements are shown below
(detailed difference between products is described in Product Overview):
Temperature
Relative Humidity
0°C to 40°C (32°F to 104°F)
10% to 90%
The temperature/humidity of working environment indicates the value measured at 1.5 m above the floor and 0.4 m
ahead of the equipment frame when there is no protection plate on the front and rear side of the equipment frame.
2.2.2 Cleanliness
The dust is also a major threat to the safe operation of device. The dust accumulated on the device may cause
electrostatic adsorption and result in poor contact. It will not only compromise the service life of device but also cause
communication failure. When the indoor relative humidity is low, such electrostatic adsorption will occur more easily.

Apart from the dust, the device is also sensitive to the hydrochloric acid sulfide contained in the air. These noxious gases
will accelerate metal wastage and the aging of certain parts. The upper limits of noxious gases (Sulfur dioxide, Sulfured

2.2.3 ESD
The router has already given consideration to electrostatic prevention during circuit design, but excessively strong static
electricity will still damage the circuit board. The static electricity in the communication network connected with the device
is mainly from:
 Outdoor high-voltage transmission line, lightning and other exterior electric fields.
 Indoor environment, flooring material, complete appliance structure and other in-house systems.
To avoid the damage caused by static electricity, we shall:
 Properly ground the device and floor.
 Apply indoor dust control.
 Maintain proper temperature and humidity.
 Before touching the circuit board, wear an anti-static wrist strap and an anti-static uniform.
 Place the circuit board disassembled face up on the antistatic workbench or in the electromagnetic shielded bag.
 When observing or transferring the circuit board of router, touch the outer edge of circuit board and avoid direct
contact with the components on the circuit board.
