from entering the chassis.
zKeep the chassis far away from the heat source.
zDo not pile up the H3C VG 80-20 Voice Gateway, so as to ensure normal heat
dissipation.
zWhen installing the unit, always make the ground connection first and disconnect it
last.
zThe unit/system must be connected to a socket-outlet with a earthing connection.
zDo not block ventilation openings while the system is on, and keep at least 5 cm
distance from ventilation openings and walls or other things which may block the
openings.
zNever defeat the ground conductor or operate the equipment in the absence of a
suitably installed ground conductor. Contact the appropriate electrical inspection.

Compliance and Safety Manual
H3C VG 80-20 Voice Gateway Chapter 3 Safety Information
3-3
zThe unit/system must be connected to the protection ground before operation
permanently. And the cross-section of protective earthing conductor shall be at
least 2.5mm2，12AWG.
zFor AC supplied model: The device applies to TN power systems.
zFor AC supplied model: The plug-socket combination must be accessible at all
times because it serves as the main disconnecting device.
zBecause the device has several power supplies, disconnect all of them to switch
off the device .
zTo reduce the risk of fire, use only No. 26 AWG or larger telecommunication line
cord.
zNo operation can be done on the device and cables when lightning.
zAs for the signal line outdoors to which the interface are connected, such as ISDN
line, telephone line, E1/T1 line, etc, a special lightning arrester should be
recommended at the input end of the signal line to enhance the lightning
protection capability.
zTo enhance the lightning protection capability of the power supply, a lightning
arrester is recommended at the input end of the power supply.
zTo avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to
telephone-network voltage (TNV) circuits. And FXS port is just for in-door use.
zWhen moving or lifting the chassis, please use the handles that are directly in the
chassis, or lift the chassis by grasping its lower edge,and it is not permitted to use
the handles on certain modules such as power supply, fans or cards, for they
cannot support the weight of the device.
zTo prevent laser radiation from hurting your eyes, never stare into the open optical
port.
zBefore operation, the equipment must be fixed securely on the floor or other
reliable objects, such as walls and mounting racks.
zIt is not recommended to wear jewelry and watch during operation on device.
zInstallation, configuration and disassembly must be done only by skillful personnel
according to the documents concerned.
zThe unit/system must be operated by experts and authorized users only.
zAny replacement or change to the system or parts of the system (including the
