the fiber port might hurt your eyes.
•Before you disconnect a fiber connector, execute the shutdown command in interface view to
disable the optical source.
•After you remove an optical fiber from the connector, install the dust cover on the connector to avoid
connector damage.
Examining the installation site
The device can only be used indoors. To ensure normal operation and a long lifespan for your device,
the installation site must meet the requirements in this section.
Temperature and humidity
Maintain the temperature and humidity in the equipment room at acceptable levels.
•Lasting high relative humidity can cause poor insulation, electricity creepage, mechanical property
change of materials, and metal corrosion.
•Lasting low relative humidity can cause washer contraction and ESD and cause problems including
loose screws and circuit failure.
•High temperature can accelerate the aging of insulation materials and significantly lower the
reliability and lifespan of the switch.
To ensure correct operation of the device, the equipment room must meet the temperature and humidity
requirements listed in Table 1.
Table 1 Temperature/humidity requirements in the equipment room
