and leads (power cords, signaling cables and output wires). To eliminate the
interferences, ensure the following:
z
For the AC power supply that adopts TN system, use a single-phase three-wire
power socket with Protection Earth (PE) to effectively filter interference from the
power grid.
z
Keep the device far from radio transmitting stations, radar stations, and
high-frequency devices.
z
Use electromagnetic shielding when necessary, for example, use shielded
interface cables.
z
Route interface cables only indoors to prevent signal ports from getting damaged
by overvoltage or overcurrent caused by lightning strikes.
2.2.4 Safety in Use of Laser
The S5100 series are class-1 laser devices.
When the extended optical interface cards on your switch are operating, do not stare
into the optical ports because the laser light emitted by the optical fiber can hurt your
retina.
Caution:
Staring into the laser beam produced by the fiber can hurt your eyes.
