ATCA-7480 Installation and Use (6806800T17A)
Safety Notes
28
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 more 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 10
ATCA-7480 boards installed each with the Spread Spectrum feature enabled. Please note that
the integrator needs to verify the EMI radiation compliancy of other configurations/settings
(for example, Spread Spectrum disabled).
Switch Settings
Blade Malfunction
Switches marked as 'reserved' might carry production-related functions and can cause the
blade to malfunction if their setting is changed.
Therefore, do not change settings of switches marked as 'reserved'. The setting of switches
which are not marked as 'reserved' has to be checked and changed before blade installation.
Blade Damage
Setting/resetting the switches during operation can cause blade damage.
Therefore, check and change switch settings before you install the blade.
Battery
Blade Damage
Wrong battery installation may result in hazardous explosion and blade damage.
Therefore, always use the same type of Lithium battery as is installed and make sure the
battery is installed as described in this manual.
