Safety recommendations
To avoid any equipment damage or bodily injury caused by incorrect use, read the following safety recommendations before installation. Note that the recommendations do not cover every possible hazardous condition.
· Before cleaning the switch, remove all power cords from the switch. Do not clean the switch with wet cloth or liquid.
· Do not place the switch near water or in a damp environment. Prevent water or moisture from entering the switch chassis.
· Do not place the switch on an unstable case or desk. The switch might be severely damaged in case of a fall.
· Ensure good ventilation of the equipment room and keep the air inlet and outlet vents of the switch free of obstruction.
· Make sure the operating voltage is in the required range.
· To avoid electrical shocks, do not open the chassis while the switch is operating or when the switch is just powered off.
· During the installation, wear a well-grounded ESD wrist strap to avoid damaging the units.
Examining the installation site
The switch must be used indoors. Mount your switch in a rack or on a workbench and verify the following items:
· Adequate clearance is reserved at the air inlet and outlet vents for ventilation.
· The rack and the workbench have a good ventilation system.
· The rack and the workbench are sturdy enough to support the switch and its accessories.
· The rack and the workbench are reliably grounded.
To ensure correct operation and long service life of your switch, install it in an environment that meets the requirements described in the following subsections.
Temperature/Humidity
Maintain appropriate temperature and humidity in the equipment room.
· Lasting high relative humidity can cause poor insulation, electricity leakage, mechanical property change of materials, and metal corrosion.
· Lasting low relative humidity can cause washer contraction and ESD and cause problems including loose mounting screws and circuit failure.
· High temperature can accelerate the aging of insulation materials and significantly lower the reliability and lifespan of the switch.
For the temperature and humidity requirements for the switch, see the hardware information and specifications of the installation guide.
Cleanliness
Dust buildup on the chassis might cause electrostatic adsorption and dust corrosion, resulting in poor contact of metal connectors and contact points. This might shorten the device's lifetime and even cause device failure in the worst case. The dust concentration limit in the equipment room is shown in the table below.

To maintain cleanliness in the equipment room, follow these guidelines:
· As a best practice, do not build the equipment room in a place with a high concentration of corrosive gases.
· Make sure the equipment room is not connected to sewer, vertical shaft, or septic tank pipelines and keep it far away from these pipelines. The air inlet of the equipment room must be away from such pollution sources.
· Use environmentally friendly materials to decorate the equipment room. Avoid using organic materials that contains harmful gases, such as sulfur or chlorine-containing insulation cottons, rubber mats, sound-proof cottons, and avoid using plasterboards with high sulfur concentration.
· Place fuel (diesel or gasoline) engines separately. Do not place them in the same equipment room with the device. Make sure the exhausted air of the engines will not flow into the equipment room or towards the air inlet of the air conditioners.
· Place batteries separately. Do not place them in the same room with the device.
· Employ a professional company to monitor and control corrosive gases in the equipment room regularly.
EMI
All electromagnetic interference (EMI) sources, from outside or inside of the switch and application system, adversely affect the switch in the following ways:
· A conduction pattern of capacitance coupling.
· Inductance coupling.
· Electromagnetic wave radiation.
· Common impedance (including the grounding system) coupling. To prevent EMI, use the following guidelines:
¡ If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE) to filter interference from the power grid.
¡ Keep the switch far away from radio transmitting stations, radar stations, and high-frequency devices.
¡ Use electromagnetic shielding, for example, shielded interface cables, when necessary.
¡ To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning strikes, route interface cables only indoors.
Laser safety
The switch is a Class 1 laser device.

Grounding the switch
|
|
WARNING! · Correctly connecting the switch grounding cable is crucial to lightning protection, ESD, and EMI protection. · Connect the grounding cable to the grounding system in the equipment room. Do not connect it to a fire main or lightning rod. · The chassis power supply and grounding terminal positions in the following figures are for illustration only. · The grounding cables are not provided with the switch. Prepare them yourself. |
The power input of the switch is connected to a noise filter, and its center grounding is directly connected to the switch, called the chassis ground (i.e., protection ground). This chassis ground must be well grounded, in order to make induced electricity and leaked electricity can safely flow into the earth, improving the electromagnetic immunity of the switch.
1. Attach the ring terminal end of the grounding cable to the grounding hole in the switch:
Remove the grounding screw from the grounding hole in the rear panel of the switch.
Attach the grounding screw to the ring terminal of the grounding cable.
Use a screwdriver to fasten the grounding screw into the grounding screw hole.
2. Connect the other end of the grounding cable to the grounding strip. And use the hex nut to secure the cable to the post.
