Laser safety
The A3100 v2 switches are Class 1 laser devices.
WARNING!
Do not stare into any fiber port when the switch has power. The laser light emitted from the optical fiber
may hurt your eyes.
Temperature/humidity
Maintain appropriate temperature and humidity in the equipment room.
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 bring problems including
loose captive screws and circuit failure.
High temperature can accelerate the aging of insulation materials and significantly lower the reliability
and lifespan of the switch.
