Safety Notes
Safety Notes
EMC
FCC Class A
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules, EN55022. These limits are designed to
provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance with the instruction
manual, can cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in
which case the user is required to correct the interference at his own expense.
To ensure EMC protection use only shielded cables when connecting peripherals to assure
that appropriate radio frequency emissions compliance is maintained. Installed blades
must have the face plates installed and all vacant slots in the shelf must be covered.
For applications where this product is provided without a face plate, or where the face plate
has been removed, your system chassis/enclosure must provide the required
electromagnetic interference (EMI) shielding to maintain EMC compliance.
Board products are tested in a representative system to show compliance with the above
mentioned requirements. A proper installation in a compliant system maintains the required
performance.
As soon as you modify the product or change the default configuration you are responsible
for complying with all relevant regulatory standards.
VCCI
This is a Class A product based on the standard of the Voluntary Control Council for
Interference by Information Technology Interference (VCCI). If this equipment is used in a
domestic environment, radio disturbance can arise. When such trouble occurs, the user is
required to take corrective actions.

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 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
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. Do not operate the blade
below -5°C.

Safety Notes
Overheating and Blade Damage
Operating the blade without forced air cooling may lead to overheating and thus damage
of the blade. 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.
