2.Direct or indirect touch through a wet object on high-voltage and mains supply may bring a fatal danger.
2.1.4 Static Discharge Damage Prevention
To prevent damage from static electricity, pay attention to the following:
1.Proper grounding of the equipment and floor
2.Indoor dust prevention
3.Proper humidity conditions
2.1.5 Laser Safety
Among the modules supported by the RG-S3250E series, a great number of optical modules are Class I laser
products. Therefore, pay attention to the following when you use them:
When a fiber transceiver works, ensure that the port has been connected with an optical fiber or is covered
with a dust cap, to keep out dust and avoid burning your eyes.
Do not stare into any optical port.
Do not stare into any optical port under any circumstances, as this may cause permanent damage to your eyes.
2.2 Installation Site Requirements
The RG-S3250E series must be used indoors. To ensure the normal working and a prolonged durable life of the
equipment, the installation site must meet the following requirements.
2.2.1 Ventilation Requirements
For the RG-S3250E series, you must ensure that sufficient space(10cm distance from both sides and the backplane
of the cabinet) is reserved at the ventilation openings to ensure the normal ventilation. After various cables have
been connected, they should be arranged into bundles or placed on the cabling rack to avoid blocking the air inlets.
2.2.2 Temperature and Humidity Requirements
To ensure the normal operation and prolong the service life of RG-S3250E series, you should keep proper
temperature and humidity in the equipment room.
If the equipment room has temperature and humidity that do not meet the requirements for a long time, the
equipment may be damaged.
In an environment with high relative humidity, the insulating material may have bad insulation or even leak
electricity. Sometimes the materials may suffer from mechanical performance change and metallic parts may
get rusted.
In an environment with low relative humidity, however, the insulating strip may dry and shrink. Static electricity
may occur easily and endanger the circuit on the equipment.
In an environment with high temperature, the equipment is subject to even greater harm, as its performance
may degrade significantly and its useful life may be shortened in the case of long-term exposure that
expedites the aging process.
Therefore, the ambient temperature and humidity of the RG-S3250E must meet the requirements listed in Table 2-1:
