System Damage
WARNING: The intra-building port (s) of the equipment or subassembly is suitable for
connection to intra-building or unexposed wiring or cabling only. The intra-building port (s) of
the equipment or subassembly MUST NOT be metallically connected to interfaces that
connect to the outside plant (OSP) or its wiring. These interfaces are designed for use as intra-
building interfaces only (Type 2 or Type 4 ports as described in GR-1089) and require isolation
from the exposed OSP cabling. The addition of primary protectors is not sufficient protection
in order to connect these interfaces metallically to OSP wiring.
The intra-building port (s) of the equipment or subassembly must use shielded intra-building
cabling/wiring that is grounded at both ends.
Operation
Blade Damage
Blade surface
High humidity and condensation on the blade surface causes short circuits.
Do not operate the blade outside the specified environmental limits. Make sure the blade is
completely dry and there is no moisture on any surface before applying power.
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.
When operating the blade in areas of electromagnetic radiation ensure that the blade is bolted
on the system and the system is shielded by enclosure.
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 more voltage on the line that has
been disconnected before continuing your work.
