2.1.5

Electromagnetic Susceptibility

Switches may be affected by the interferences from outside the system, which will have an effect on devices

through conduction of c

apacitance coupling, inductive coupling, electromagnetic wave radiation, common

impedance (including ground system) coupling and wires (power wire, signal wire and output signal wire, etc.).

The following attention should be paid to:



AC power supply system

is TN system, and AC power socket should be single

phase 3

wire outlet

with protective earth (PE) so that filter circuit on devices can effectively filter interference from

electric

grid



Places where switches work should be kept away from strong

power ra

dio transmitting station, radar

transmitting station, high

frequency high

current devices.



Electromagnetic shielding should be adopted when necessary,

i.e

. interface cables use shielded

cables.



Interface cables are required to be arranged indoors instead o

f outdoors to prevent signal ports of

devices from being damaged by

over voltage

and

over current

generated from lightning.

2.1.6

Laser Use Safety



9171

series of routing switches are Class 1 laser devices.



Do not stare at the optical interfaces directly when th

e optional optical interfaces of

9171

series of

routing switches are in operating mode, since light beam emitting from fiber has high energy which

may be harmful to retina.
