Installation Manual
H3C S5500-SI Complete Series Ethernet Switches
As the AC power system is a TN system, use a single-phase three-wire power
socket with Protection Earth (PE) to effectively filter interference from the power
grid.
Keep the device far from radio transmitting stations, radar stations, and
high-frequency devices.
Use electromagnetic shielding when necessary, for example, use shielded
interface cables.
Route interface cables only indoors to prevent signal ports from getting damaged
by overvoltage or overcurrent caused by lightning strikes.

2.2.4 Laser Safety

The S5500-SI series are Class 1 laser devices.
When the extended optical interface cards on the S5500-SI series are operating, do not
stare into the optical ports because the laser light emitted by the optical fiber may hurt
your retina.
Caution:
Staring into the laser beam produced by the fiber may hurt your eyes.
