L2 Lite Managed Switch
TL-SL3428
Please keep a pro per temperature and humidity in the equip ment room. Too high/low
humidity may lead to bad insulation, elect ricity leakage, mechanical property changes
and corrosions. Too high tempe rature may accelerate aging of the insulation materials
and can thus significantly shorten the service life of the device. For normal tempe rature
and humidity of the device, please check the following table.
Environment Temperature Humidity
Operating 0℃ ~ 40℃10% ~ F0%RH Non-condensing
Storage -40℃ ~ F0℃5% ~ F0%RH Non-condensing
Clearness
The dust ac cumulated on t he Switch can be absorbe d by static electricity and result
in poor contac t of metal co ntact p oints. Some mea sures ha ve been taken for the
device to prevent static electricity, b ut too st rong static electricity can cause deadly
damage to the electronic elements on the inter nal circuit board. To avoid the e ffect of
static electricity on the operation of the Switch, please attach much impor tance to the
following items:
Dust the device regularly, and keep the indoor air clean.
■
Keep the device well grounded and ensure static electricit y has been transferred.
■
Electromagnetic Interference
Electronic elements including capacitance and inductance on the device can be affe cted
by ex ternal interf erences , such as conduc ted e mission by capacit ance c oupling,
inductance coup ling, and impe dance coupling. To decrease the interference s, please
make sure to take the following measures:
Use the power supply that can effectively filter inter ference from the power grid.
■
Keep the device far fr om high-f requency, strong-curr ent devic es, such as radio
■
transmitting station.
Use electromagnetic shielding when necessar y.
