2.2 Requirements on Environment
S3100-SI series must be used indoors. When you install your
switch in a cabinet or install it directly on a workbench, you must
ensure:
ensure:
z
Enough space is left near the air-intake hole and the
ventilation hole of the switch for the heat dissipation of the
switch chassis.

z
The cabinet or the workbench is well grounded.
To ensure normal operation and to prolong the life span of the
switch, the following requirements on the installation site must also be
satisfied.
satisfied.
2.2.1 Temperature/Humidity Requirements
You should keep your equipment room within the proper
temperature and humidity ranges to ensure the normal operation and
working life of your switch. If the humidity in the equipment room is too
high for a long time, it may decrease the insulation attribute of
insulating material or even cause electric leakage of insulating
material, and, sometimes, may change the mechanical performance
of material and cause the rustiness and corrosion of metal parts. If the
relative humidity is too low, the captive screws may become loose due
to the shrinking of insulation washers; in addition, electrostatic is more
likely to be produced in a dry environment, which may damage the
circuit of the switch. High temperature may cause even greater
working life of your switch. If the humidity in the equipment room is too
