Emi; Laser Safety; Installation Tools - HP FlexNetwork 5120 SI Series Installation Manual

EMI

All electromagnetic interference (EMI) sources, from outside or inside of the switch and application
system, adversely affect the switch in the following ways:

A conduction pattern of capacitance coupling.

Inductance coupling.

Electromagnetic wave radiation.

Common impedance (including the grounding system) coupling.
To prevent EMI, perform the following tasks:

If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE)
to filter interference from the power grid.

Keep the switch far away from radio transmitting stations, radar stations, and high-frequency
devices.

Use electromagnetic shielding, for example, shielded interface cables, when necessary.

Laser safety

The switch is Class 1 laser device.
WARNING!
Do not stare into any fiber port when the switch has power. The laser light emitted from the optical
fiber might hurt your eyes.
