Static Discharge Damage Prevention - Ruijie RG-S7808C Series Hardware Installation And Reference Manual

Find out the location of the emergency power supply switch in the room before installation. First cut off the power
supply in case of an accident.
Be sure to make a careful check before you shut down the power supply.
Do not place the equipment in a damp/wet location. Do not let any liquid enter the chassis
Any nonstandard and inaccurate electrical operation can cause an accident such as fire or electrical attack, thus
causing severe even fatal damages to human bodies and equipment.
Direct or indirect touch through a wet object on high-voltage and mains supply can bring a fatal danger.

2.1.4 Static Discharge Damage Prevention

Although much has been done in RG-S7808C to prevent static electricity, great damage may be caused to the circuitry
and equipment when the static electricity exceeds a certain limit. In the communication network of the RG-S7808C,
electrostatic induction may come from the following sources: External electric field produced by the high-voltage supply
cable, lightning, etc; internal systems such as the indoor floor and the entire structure.
To prevent damage from static electricity, you must pay attention to the following:
Properly ground the equipment.
Take dust prevention measures in the room.
Maintain an appropriate humidity.
Always wear an anti-static wrist strap when you touch any circuit board.
Try to hold a circuit board by its edges. Do not touch any components or the PCB.
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.
The S7808C series switches are equipped with an anti-static wrist strap. Please refer to Figure 2-1 for the position of
the jack for the wrist strap.
The S7808C series switches are equipped with an anti-static wrist strap. To protect electronic components against static
electricity, wear an anti-static wrist strap close to your skin and keep it properly grounded while installing swappable
modules.
Use an anti-static wrist strap as follows:
1. Ensure that the switch is properly grounded.
2. Put your hand in the anti-static wrist strap.
3. Tighten the buckle till the trap is closely attached to your skin.
For safety, use a multimeter to measure the resistance between yourself and the ground, which should be within the
range
Make sure that the switch is properly grounded when the anti-static wrist strap is connected to the ground through
the chassis jack.
