Safety Precautions
Observe the following precautions when handling the equipment:
•
Power ON/OFF: The push-button on/off power switch on the front panel of the
BorderNet 4000 SBC does not turn off the power.
•
For AC systems, if power needs to be removed from this product, you must
disconnect the power cord; therefore, the socket-outlet shall be installed near
the equipment and shall be easily accessible.
•
For DC systems, additional readily accessible disconnect devices, like circuit
breakers or power switches, must be incorporated in the building installation
wiring.
•
Warning – This system may contain more than one power supply. Disconnect
all power supplies before servicing.
•
Power supply: Hazardous voltage, current, and energy levels are present inside the
power supply enclosure.
•
Devices and cables: Hazardous electrical conditions may be present on power,
telephone, and communication cables. Turn off the BorderNet 4000 SBC and
disconnect telecommunications systems, networks, modems, and the power cord
attached to the BorderNet 4000 SBC before opening it. Otherwise, personal injury or
equipment damage can result.
•
Maintenance: There are no user-serviceable parts inside the BorderNet 4000 SBC.
Only technically qualified personnel approved by Dialogic should perform service and
maintenance tasks.
•
Avoid injury: Lifting the BorderNet 4000 SBC and attaching it to the rack is a two-
person job. If needed, use an appropriate lifting device.
•
Electrostatic Discharge Protection (EDP): Use proper ESD protection.
Electrostatic Discharge (ESD) protective straps, shoes, or mats must be used when
working with electronic components. Electrostatic discharge from your body can
damage integrated circuits during installation.
•
DC systems: For DC systems, each unit should be on its own branch circuit. The
over-current protection device of the branch circuit must be rated a maximum of 30
A. The DC power supply of this equipment is fitted with a DC fuse rated 30A.
•
DC Power Supply Wiring: Only wires rated minimum 12 AWG and VW-1 or FT-1
are to be used to connect to the DC power source.
•
Uneven loading: Use caution when mounting the equipment in the rack so that a
hazardous condition is not achieved due to uneven mechanical loading.
•
Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries
according to the battery manufacturer’s instructions.
•
For AC input version, this product is equipped with a three-wire grounding type plug,
a plug having a third (grounding) pin. This plug is intended to fit only into a
grounding type power outlet. This is a safety feature. If you are unable to insert the
plug into the outlet, contact your electrician to replace your obsolete outlet. Do not
defeat the safety purpose of the grounding type plug. Do not use a 3-to-2 prong
adapter at the receptacle. Use of this type adapter may result in risk of electrical
shock and/or damage to this product.
