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

Caution:
When an optional interface module or SFP module on the S5500-EI series is operating,
do not stare into the optical port because the laser light emitted from the optical fiber
may hurt your eyes.
