Blade Overheating and Blade Damage
Operating the blade without forced air cooling may lead to blade overheating and thus
blade damage.
When operating the blade, make sure that forced air cooling is available in the shelf.
Injuries or short circuits
Blade or power supply
In case the ORing 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.
Hot Swap
Installing the blade into or removing it from a powered system not supporting hot
swap or high availability causes blade 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.
Removing the blade from the backplane while the hot−swap LED is still off causes
data loss. Therefore, wait until the blue hot−swap LED is on before removing the
blade.
Replacement/Expansion
Only replace or expand components or system parts with those recommended by
Motorola. 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).
Replacement/Expansion
Only replace or expand components or system parts with those recommended by
Motorola. Otherwise, you are fully responsible for the impact on EMC or any possible
malfunction of the product.
As the blade is current protected, an overcurrent results in a power−down of the blade
if an overcurrent occurs. Make sure that the max. power consumption per PMC slot at
+/−12V, 5V and 3.3V level does not exceed 7.5W (total overall used voltages).
