• General Maintenance Guidelines

NCT480 IP DSLAM User Guide YML856 Rev3
16 www.netcomm.com.au
Safety Guidelines
Before working on the equipment, be aware of standard safety guidelines and the hazards that are involved
in working it electrical circuitry to prevent accidents. Adhere to the following cautions and warnings and those
throughout the guide for safe and hazard-free installation.
Only trained and qualified personnel should be allowed to install or replace this equipment.
Before removing the equipment, disconnect the telephone-network cables to avoid contact with telephone-network voltages.
Do not work on system or connect or disconnect cables during periods of lightning activity.
Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote risk of electric shock from
lightning.
Read the power instructions before you connect the system to its power source.
For safety reason, the ground wire must connect to safety (earth) ground at supply side of the AC wiring; ensure that the host is
connected to earth ground during the normal use.
To reduce the risk of electric shock when servicing any individual unit, disconnect the power cord or cords that connect the unit to the
AC power strip or DC bus bar.
Two people are required to lift the box. Grasp the box underneath the lower edge and lift with both hands. To prevent injury, keep your
back straight and lift with your legs, not your back.
To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system
remains stable. The following guidelines are provided to ensure your safety:
• When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the
bottom of the rack
• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack
Ethernet cable must be shielded when used in a central office environment.
This unit is intended for installation in restricted access areas, A restricted access area is where access can only be gained by service
personnel through the use of a special tool, lock and key, or other means of security, and is controlled by the authority responsible for
the location.
To reduce the risk of fire, use only No. 36 AWG or larger telecommunication line cord.
Use copper conductors only.
Never touch un-insulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
Use caution when installing or modifying telephone lines.
Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects
will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports
contain SELV circuits and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when
connecting cables.
Ultimate disposal of this product should be handled according to all national laws and regulations.
Do not use this product near water; for example, near bath tub, wash bowl, kitchen sink or laundry tub, in a wet basement, or near a
swimming pool.
Do not use this product near water; for example, near bath tub, wash bowl, kitchen sink or laundry tub, in a wet basement, or near a
swimming pool.
Never install telephone RJ-21 connector in wet locations unless the connector is specifically designed for wet locations.
Do not use a telephone to report a gas leak in the vicinity of the leak.

Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) is a transfer of electrostatic charge between bodies of different electrostatic
potentials, such as an operator and a piece of electrical equipment. It occurs when electronic components are
improperly handled, and it can damage equipment and impair electrical circuitry. Electrostatic discharge is
more likely to occur with the combination of synthetic fibers and dry atmosphere.
Use an antistatic strap during removing and replacing NCT480 units.
Always use an ESD ankle or wrist strap and ensure that it makes good skin contact.
To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively.
Do not touch any exposed contact pins or connector shells of interface ports that do not have a cable attached. If cables are connected
at one end only, do not touch the exposed pins at the unconnected end of the cable.
This equipment is intended for use in residential and commercial environments only.
Periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohms (Mohms).
General Maintenance Guidelines
The following maintenance guidelines apply to NCT480 system units:
Keep the NCT480 box area clear and dust-free during and after installation.
If you remove the chassis cover for any reason, store it in a safe place.
Do not perform any action that creates a hazard to people or makes equipment unsafe.
Keep walk areas clear to prevent falls or damage to equipment.
