Notice
A sample of ambient temperature and humidity should be taken at 1.5m above the floor and 0.4m in front of the switch rack, with no protective panel covering the front and rear of the rack.
Short term working conditions refer to a maximum of 48 hours of continued operation and an annual cumulative total of less than 15 days.
Formidable operation conditions refers to the ambient temperature and relative humidity value that may occur during an
2.1.3Dust and Particles
Dust is harmful to the safe operation of the ES4710BD. Dust can lead to electrostatic adherence, especially likely under low relative humidity, causing poor contact of metal connectors or contacts. Electrostatic adherence will result in not only reduced product lifespan, but also increased chance of communication failures. The recommended values for dust content and particle diameter in the site are shown below:
Max. Diameter (µm) | 0.5 | 1 | 3 | 5 | |
Max. Density | 1.4×107 | 7×105 | 2.4×105 | 1.3×105 | |

In addition, salt, acid and sulfide in the air are also harmful to the switch. Such harmful gases will aggravate metal corrosion and the aging of some parts. The chosen site should avoid harmful gases, such as SO2, H2S, NO2, NH3 and Cl2, etc. The table below details the threshold values.
Gas | Average (mg/m³) | Max (mg/m³) |
SO2 | 0.2 | 1.5 |
H2S | 0.006 | 0.03 |
NO2 | 0.04 | 0.15 |
NH3 | 0.05 | 0.15 |
Cl2 | 0.01 | 0.3 |
