Safety Precautions
Thunderstorms
Do not work with electrical current or work in elevated or exposed locations during a thunderstorm.
Extreme weather conditions
OAU 2F is usually installed outdoors. If weather conditions are extreme during an installation, personnel
should follow the related local guidelines and regulations to safeguard personal health and safety.
Microwave
High-power radio frequency signals are harmful. Avoid exposure to transmission from the antennas of
microwave equipment that has the radiation warning symbol ( ). When you are installing or
performing maintenance on an antenna located on a tower that has multiple antennas, avoid exposure to
radiation from other antennas.
Elevated locations
OAU 2F is usually installed in an elevated location, for example, on the rooftop of a building. For installation
in elevated locations, installation personnel must:
Have the proper training and qualifications, and meet health requirements.
Wear helmets, safety belts, and anti-slip footwear.
Wear clothing and gloves appropriate to weather conditions.
Work in teams of two or more.
Test hoisting tools before use.
Avoid installation during extreme weather conditions, such as during thunderstorms, blizzards, or gales.
In addition, all site visitors must wear helmets.
High temperature
If the ambient temperature reaches 55°C, the surface temperature of an OAU 2F may exceed 70°C.
Therefore, wear protective gloves when handling the OAU 2F. A high-temperature warning label ( ) is
attached to each OAU 2F.
Corrosion
Anti-corrosion measures are required if an OAU 2F is installed in a location that is prone to corrosion. Contact the
local Huawei office for details. A location is prone to corrosion if it is:
Within 3.7 km of an ocean or a salt water lake
Within 3 km of a heavy pollution source, such as a smelting factory or coal mine
Within 2 km of a medium pollution source, such as a chemical, rubber, or electroplating plant
Within 1 km of a light pollution source, such as a food/leather processing plant or heating boiler
Unpacking
After unpacking an OAU 2F, power it on within 24 hours.
Do not power off an OAU 2F for more than 24 hours during maintenance.
Handling of OAU 2F or mounting kits
Wear clean gloves when handling the OAU 2F or mounting kits.
Moving and hoisting heavy objects
To move or hoist heavy objects, use appropriate equipment and adhere to the
following guidelines:
All personnel should wear helmets and protective clothes, gloves, and shoes.
Move heavy objects along a flat obstacle-free path.
Do not lift heavy objects by hand. Use appropriate equipment instead.
When items are hoisted, ensure that those standing nearby are safe from falling objects.
Use hoisting tools properly. Do not exceed load allowances to prevent damage to pulleys or slings.
Lasers
Do not look into an optical port without eye protection.
Local rules and regulations
If local rules and regulations require that anti-corrosion measures must be taken for ground connections, comply with
local rules and regulations.

Safety Precautions
DC power
The OAU 2F (DC option) supports only DC power supply. The OAU 2F (P&E option) supports only P&E power
supply.
Do not install or remove a live power cable. Any contact between the power cable core and a conductor can
generate electric arc or sparks, which may cause fire or eye injury.
Connect the power cables correctly to the positive and negative terminals of the power supply device. The
recommended fuse capacity is 7 A to 10 A.
Do not connect the OAU 2F to an AC power supply device. Otherwise, the OAU 2F may be damaged.
Do not connect the OAU 2F to a DC power supply device providing power beyond the range of –38.4 V to –57.6 V.
Otherwise, the OAU 2F may be damaged.
Do not leave any service cable unconnected.
Do not leave any service cable unconnected (see the following figure).
If a service port is not in use, remove the cable from it and plug it with a waterproof block.
IF port protection
If an IF port is not in use, cover it with a protective cap delivered with the equipment.

The model recommended for the USB flash drive is Netac
U208 with a 4 GB capacity.
If a different model or capacity is required, contact Huawei
local offices.
The appearance of Netac U208 flash drives varies
depending on the vendor.
Only USB 2.0 is supported.

If the OAU 2F (DC option) uses DC power, do not install
or remove a live power cable. Any contact between the
power cable core and a conductor can generate electric
arc or sparks, which may cause fire or eye injury.
This document uses outdoor optical fiber
installation as an example to describe the methods
of installing cables. Methods of installing the
outdoor Ethernet cables are the same as those of
installing the outdoor optical fiber.
After the equipment is installed and commissioned,
the methods and procedure for cable replacement
and expansion are the same as those described in
the figures.
Socket expansion caps and rubber plug are used
for anti-falling. Do not pull them off forcibly.

When installing a lightning surge protector, separate the protector
from the RTN device with a spacing of no less than 10 cm. This
ensures that cables between the protector and SFP GE electrical
modules can be used for efficient decoupling.

Select ground points for the outdoor network cable.
Ground the outdoor network cable at the following positions:
1. About 0.5 m to 1 m away from the port
2. About 1 m before the cable leaves the tower and runs toward the outdoor cable tray
3. About 1 m before the cable leaves the roof cable ladder
Select ground points for the DC cable.
Ground the DC cable at the following positions:
1. About 0.5 m to 1 m (1.64 feet to 3.28 feet) before the cable is routed into the equipment room or outdoor cabinet
2. About 1 m before the cable leaves the tower and runs toward the outdoor cable tray
3. About 1 m before the cable leaves the roof cable ladder

Installing a ground clip
Install and waterproof the ground clip. (See the appendix for the waterproofing method.)
Use a box cutter to strip off a section of the cable sheath. Take care not to damage the shield layer.
If a ground clip is installed on a thin cable,
secure the ground clip by using the binding
wire delivered with the ground clip.
For details about how to install ground clips,
see the use instructions delivered with the
ground clips.
Ensure that the angle between a PGND cable and a power cable is
15 degrees or less. If the power cable is routed vertically, route the
PGND cable from the top downwards. Do not route the ground
cable upwards.
