z
The rack or table/workbench has a good ventilation system.
z
The rack is sturdy enough to support the device and its
accessories.
z
The rack or table/workbench is well earthed.
To ensure normal operation and long service life of an S5100
switch, install it in an environment that meets the requirements
described in the following subsections.
2.2.1 Temperature/Humidity
You need to maintain a proper temperature and humidity in the
equipment room.
z
Long-term high humidity may lead to bad insulation,
electricity leakage, mechanical property changes, and
corrosion.
z
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 circuits on the device.
z
High temperature is the most undesirable condition,
because it accelerates aging of insulation materials and can
thus significantly lower reliability and service life of your
switch.
For the detailed temperature/humidity requirements for the
products, see section 1.3 System Features of the S5100 Series.
