2.1 Safety Precautions
To avoid any device impairment and bodily injury caused by improper use, observe
these rules:
z Before cleaning the switch, unplug the power plug of the switch first. Do not clean
the switch with wet cloth or liquid.
z Do not place the switch near water or any damp area. Prevent water or moisture
from entering the switch chassis.
z Do not place the switch on an unstable case or desk. The switch might be
damaged severely in case of a fall.
z Ensure proper ventilation of the equipment room and keep the ventilation vents of
the switch free of obstruction.
z Make sure that the operating voltage is the same one labeled on the switch.
z Do not open the chassis while the switch is operating or when electrical hazards
are present to avoid electrical shocks.
z When replacing interface cards, wear an ESD-preventive wrist strap to avoid
damaging the cards.
2.2 Installation Site
The S3600 series must be used indoors. You can mount your switch in a rack or on a
desktop/workbench, but make sure:
z Adequate clearance is reserved at the air inlet/exhaust vents for ventilation.
z The rack or desk has a good ventilation system.
z The rack is sturdy enough to support the device and its accessories.
z The rack or desk is well earthed.
To ensure normal operation and long service life of your VG, install it in an environment
that meets the requirements described in the following subsections.
2.2.1 Temperature/Humidity
You must maintain a proper temperature and humidity in the equipment room.
Long-term high humidity may lead to bad insulation, electricity leakage, mechanical
property changes, and corrosion. However, if the relative humidity is two low, captive
screws may become loose as the result of contraction of insulation washers and static
electricity may be produced in a dry environment to jeopardize the CMOS circuits on
the device. High temperature is the most undesirable condition, because it accelerates
