Safety Notes
Centellis 2x00 User Card-10GE Installation and Use (6806800H33E) 17
Operation
Board Damage–Board Surface
High humidity and condensation on the board surface causes short circuits.
Do not operate the board outside the specified environmental limits. Make sure the board
is completely dry and there is no moisture on any surface before applying power.
Board Overheating and Board Damage
Operating the board without forced air cooling may lead to board overheating and thus
board damage.
When operating the board, make sure that forced air cooling is available in the shelf.
Injuries or Short Circuits–Board or Power Supply
In case the ORing diodes of the board fail, the board 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.
Hot Swap
Installing the board into or removing it from a powered system not supporting hot swap or
high availability causes board damage and data loss. Therefore, only install it in or remove
it from a powered system if the system itself supports hot swap or high availability and if the
system documentation explicitly includes guidelines.
Replacement/Expansion
Only replace or expand components or system parts with those recommended by SMART
EC. Otherwise, you are fully responsible for the impact on EMC or any possible malfunction
of the product.
Check the total power consumption of all components installed (see the technical
specification of the respective components). Ensure that any individual output current of
any source stays within its acceptable limits (see the technical specification of the
respective source).
Environment
Always dispose of used products according to your country’s legislation and
manufacturer’s instructions.
