JetStream L3 Stackable Managed Switch

06 Preparing for Installation

Please keep a proper temperature and humidity in the equipment room. Too high/low humidity may

lead to bad insulation, electricity leakage, mechanical property changes and corrosions. Too high

temperature may accelerate aging of the insulation materials and can thus significantly shorten

the service life of the device. For normal temperature and humidity of the device, please check the

following table.

Clearness

The dust accumulated on the switch can be absorbed by static electricity and result in poor contact

of metal contact points. Some measures have been taken for the device to prevent static electricity,

but too strong static electricity can cause deadly damage to the electronic elements on the internal

circuit board. To avoid the effect of static electricity on the operation of the Switch, please attach

much importance to the following items:

■

Dust the device regularly, and keep the indoor air clean.

■

Keep the device well grounded and ensure static electricity has been transferred.

Electromagnetic Interference

Electronic elements including capacitance and inductance on the device can be affected by

external interferences, such as conducted emission by capacitance coupling, inductance coupling,

and impedance coupling. To decrease the interferences, please make sure to take the following

measures:

■

Use the power supply that can effectively filter interference from the power grid.

■

Keep the device far from high-frequency, strong-current devices, such as radio transmitting station.

■

Use electromagnetic shielding when necessary.

Lightening Protection

Extremely high voltage currents can be produced instantly when lightning occurs and the air in

the electric discharge path can be instantly heated up to 20,000

℃

. As this instant current is strong
