Caution:
The laser inside the optical fiber may hurt your eyes.
2.2 Examining Installation Site
The S9500 series can only be used indoors. To ensure that the switch works normally
and to prolong its service lifetime, the following requirements should be met in terms of
installation environment.
2.2.1 Temperature Requirements
To ensure the normal operation of a switch, the temperature in the room should be
maintained within a proper range. Table 2-1 describes temperature requirements.
Table 2-1
Temperature requirements

Range
Operating temperature
0°C to 45°C (32°F to 113°F)
Storage temperature
–40°C to +70°C (–40°F to 158°F)
The higher the temperature, the greater the damage it will do to the switch. Long-lasting
high temperature will speed up the aging process of the insulating materials, greatly
lower the reliability of the switch, and therefore affect its service life seriously.
Caution:
After the switch is moved to a high-temperature location, if condensate appears on the
switch, you must dry the switch before power-on, thus to avoid damaging interior
components due to short circuit.
2.2.2 Humidity Requirements
To ensure the normal operation of a switch, the humidity in the equipment room should
be maintained within a proper range. Table 2-2 describes humidity requirements.
