Precautions
Following All Safety Precautions
Before any operation, read the instructions and precautions in this document carefully to minimize the possibility
of accidents.
The Danger, Caution, and Note items in the documents do not cover all the safety precautions that must be
followed. They only provide the generic safety precautions for operations.
When operating Huawei products and equipment, you must comply with safety precautions and special safety
instructions related to corresponding equipment provided by Huawei. The safety precautions in the document are
related to only Huawei products. Huawei is not liable for any consequence that results from the violation of
universal regulations for safety operations and safety codes on design, production, and equipment use.
Complying with the Local Safety Regulations
When operating the product or equipment, comply with local safety regulations.
Qualified Personnel Only
Installation and maintenance personnel must be trained to perform operations correctly and safely.
Personnel Safety
The high-voltage power supply provides power for running the system. Avoid direct contact with the high-voltage
power supply or contact through damp objects. Failure to do so causes serious injury or death.
Non-standard and incorrect operations on the high-voltage power supply may result in fire and electric shock.
Do not perform operations on high-voltage and AC power supply facilities or on a tower or mast in the case of
thunderstorm. Failure to do so causes serious injury or death.
Ground the device before powering it on. Failure to do so causes damage to the device or personal injury.
Power off the device before performing operations on the power supply facilities.
Personnel Safety
High power radio-frequency signals are harmful to the human body. Ensure that the transmitter antennas are
muted before installing or maintaining an antenna on a tower or mast that holds a large number of transmitter
antennas.
Do not stand close to, or look into the optical fiber outlet without eye protection when handling optical fibers.
Take preventive measures when drilling holes. Otherwise, dust may hurt your eyes or you may inhale the dust.
When working at heights, be cautious about falling objects.
Device Safety
Check the electrical connection of the device before operation and ensure that the device is securely grounded.
The static electricity discharged from the human body may damage the electrostatic sensitive components, such
as large-scale integrated circuits (LSIs), on the circuit board. Wear an ESD wrist strap or ESD gloves when
handling a circuit board.

2
Do not hold a board without hand protection. Wear an ESD wrist strip or ESD gloves before handling
a board.
Insert filler panels into vacant slots on an NE to prevent foreign matters from getting into the NE,
which may result in faults on the NE.
Boards are fragile and valuable. When handling or placing a board, exercise caution and put it
into a dedicated packing box.
Holding a board without hand
protection
Wearing ESD gloves Wearing an ESD strip
Hold the front panel of a board with hands.

Installing the OMB cabinet on a pole Installing the OMB cabinet on a wall
The OMB cabinet provides a small space. Therefore, it is not recommended that you use the OMB cabinet in
an area where the ambient temperature is lower than –20°C in winter. It is recommended that you use the
APM30H or TMC11H cabinet that is configured with a heater.

Installing the PGND Cables for the Cabinet
a
When installing the PGND cables
in the DC powered OMB cabinet,
use the same method as that in
the AC powered OMB cabinet.
The ground cables and signal
cables must be bound separately
or must be separated from each
other for certain spacing to
minimize mutual interference.
The PGND cables are in yellow-
green color. The general ground
cable has a cross-sectional area
of 16 mm2.
