Safety Notes
30 ATCA-7540 Installation and Use (6806871A01A )
Operating the product in a residential area is likely to cause harmful interference. If this occurs,
the user will be required to correct the interference at the user's expense.
Changes or modifications not expressly approved by Artesyn could void the user's regulatory
compliance. Board products are tested in a representative system to show compliance with the
above mentioned requirements. A proper installation in a compliant system will maintain the
required performance.
Use only shielded cables when connecting peripherals to assure that appropriate radio
frequency emissions compliance is maintained. For proper EMC shielding, only operate the
system with faceplates installed and all vacant slots covered or populated with filler cards.
The COM, ETH, and USB interfaces are considered debug/maintenance ports. During normal
operation, no cables should be connected to these ports. Cables attached to these ports
during maintenance must not exceed a length of 10 feet (3 meters).
This is a Class A product based on the standard of the Voluntary Control Council for
Interference (VCCI) by Information Technology Interference. If this equipment is used in a
domestic environment, radio disturbance may arise. When such trouble occurs, the user may
be required to take corrective actions.
NOTE: This product has been tested and shipped with the Spread Spectrum Clock (SSC)
function disabled. Artesyn does not guarantee functional or EMC compliance with SSC
enabled.
Installation
Damage of Circuits
Electrostatic discharge and incorrect product installation and removal can damage circuits or
shorten their life.
Before touching the product or electronic components, make sure that you are working in an
ESD-safe environment. Hold the product by its edges and do not touch any components or
circuits.
