EMI
All electromagnetic interference (EMI) sources, from outside or inside of the switch and application
system, adversely affect the switch in a conduction pattern of capacitance coupling, inductance coupling,
electromagnetic wave radiation, or common impedance (including the grounding system) coupling. To
prevent EMI, take the following actions:
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.
Route interface cables only indoors to prevent signal ports from getting damaged by overvoltage or
•
overcurrent caused by lightning strikes.
Laser safety
The HP FlexFabric 5930 switches are Class 1 laser devices.
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.
