Safety Instruction
The following is the safety instructions for SmartDSLAM before installation:
1. Read and follows all warning notices and instructions of this user manual.
2. The maximum recommended operating temperature for the SmartDSLAM is
50ºC. Care must be taken to allow sufficient air circulation or space between
units when the SmartDSLAM is installed inside a closed rack assembly and
racks should safely support the combined weight of all SmartDSLAM.
3. The connections and equipment that supply power to the SmartDSLAM
should be capable of operating safely with the maximum power requirements of
the SmartDSLAM. In the event of a power overload, the supply circuits and
supply wiring should not become hazardous.
4. The AC adapter must plug in to the right supply voltage. Make sure that the
supplied AC voltage is correct and stable. If the input AC voltage is over 10%
lower than the standard may cause the SmartDSLAM to malfunction.
5. Do not allow anything to rest on the power cord of the AC adapter, and do not
locate the product where anyone can walk on the power cord.
6. Generally, when installed after the final configuration, the product must
comply with the applicable safety standards and regulatory requirements of the
country in which it is installed. If necessary, consult for technical support.
7. A rare condition can create a voltage potential between the earth grounds of
two or more buildings. If products installed in separate building are
interconnected, the voltage potential can cause a hazardous condition. Consult
a qualified electrical consultant to determine whether or not this phenomenon
exists and, if necessary, implement corrective action before interconnecting the
products. If the equipment is to be used with telecommunications circuit, take
the following precautions:
•
Never install telephone wiring during a lightning storm.
•
Never install telephone jacks in wet location unless the jack is specially
designed for wet location.
•
Never touch uninsulated telephone wires or terminals unless the telephone
line has been disconnected at the network interface.
•
Use caution when installing or modifying telephone lines (other than a cordless
telephone) during an electrical storm. There is a remote risk of electric shock
from lightning.
•
Do not use a telephone or other equipment connected to telephone lines to
