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.
