Any nonstandard and inaccurate electrical operation can cause accidents such as fires or electrical attacks, thus
causing severe, or even fatal damages to human bodies and the devices.
Direct or indirect touch through a wet object on high-voltage and mains supply can bring a fatal danger.
2.1.4 Electrostatic Discharge Damage Precautions
The RG-S6920-4C designing gives a great consideration to prevent electrostatic discharge damage and adopts
multiple measures. But if the electrostatic exceeds certain limit, it can still cause great damages to the circuitry and the
device. In networks connected by the RG-S6920-4C, the major sources of electrostatic induction are outdoor high
voltage transmission cables, lightening, indoor floor materials and the machine structure.
Pay attention to the following tips:
The device and the floor are well grounded.
Take dust prevention measures in the room.
Maintain an appropriate humidity.
When the pluggable modules of the switch are being installed, wear antistatic wrist strap and make sure the
antistatic wrist strap is well grounded.
Do not use bare hand to directly touch the components and the printed-circuit board (PCB) when the boards are
used.
Use an anti-static shielding bag to properly store the board.
Do not let any clothes touch a circuit board. An antistatic wrist strap can only prevent human static electricity from
damaging the circuit board, but cannot prevent any static electricity on clothes.
2.1.5 Laser Safety
Among the modules supported by the RG-S6920-4C, there are a great number of optical modules that are Class
I
laser
product.
Precautions:
When a fiber transceiver works, ensure that the port has been connected with a fiber or has been covered by a
dust cap so as to keep out dust and prevent it from burning your eyes.
Do not stare at any fiber port.
Do not stare at any fiber port under any circumstances, as this may cause permanent damage to your eyes.
2.2 Installation Site Requirements
Install the RG-S6510 indoor. To ensure normal operation and a prolonged service life of the device, the installation site
must meet the following requirements.
2.2.1 Rack Mounting Requirements
Make sure the cabinet complies with the following conditions if the RG-S6920-4C is installed in the cabinet:
