Safety Notes
32 ATCA-7540 Installation and Use (6806871A01A )
When operating the product in areas of electromagnetic radiation, secure the product in the
system using the front panel screws. Make sure the product is fully shielded by the enclosure.
Data Corruption
If power to the unit is removed while a firmware update is in progress to the product's flash
memory, the changes will not be saved or the flash memory may be corrupted. In such case,
the product is likely to remain in non-operable state and will require reconditioning by
qualified repair services.
Injuries or Short Circuits — Blade or Power Supply
In case the O-Ring diodes of the blade fail, the blade may trigger a short circuit between input
line A and input line B so that line A remains powered even if it is disconnected from the power
supply circuit (and vice versa).
To avoid damage or injuries, always check that there is no voltage on the line that has been
disconnected before continuing your work.
The EMI radiation compliancy of the product has been qualified in a reference system with the
Spread Spectrum feature disabled. Please note that the integrator needs to verify the EMI
radiation compliancy of other configurations/settings (for example, Spread Spectrum
enabled).
Switch Settings
Blade Malfunction
Do not change settings of switches marked Reserved . Switches marked Reserved might carry
production-related functions and can cause the blade to malfunction if setting is changed.
Check and change the setting of any switch not marked Reserved before installing the blade.
Blade Damage
Check and change switch settings before you install the blade.
Setting/resetting the switches during operation can cause blade damage.
