0. Preface
0.1. Safety Instructions
1) Grounding:The access unit and extension unit of the device are equipped with protective grounding terminals.
During installation, yellow-green grounding wires should be used to ensure a reliable connection to the building’s
protective earth. Grounding braided straps may also be used. The antenna and feeder cables must be properly
grounded.
2) Power Supply:The device supports DC 48V power supply or AC 220V (198–240V) power supply. Please
ensure that the DC power source is within the device’s required range of DC 36–60V. The grounding
terminal of the device must be reliably connected to the building’s protective earth.
3) Electric Shock Protection:Touching the internal power module of the device is dangerous. Live operation is
strictly prohibited to prevent electric shock.。
4) Optical Module:The optical module supports hot-swapping, but the fiber optic connector must not be pointed at
any part of the human body during insertion or removal.
5) Surge Protection:
The built-in surge protector of this product is mainly designed to protect against induced lightning
and switching overvoltage. It cannot protect against direct lightning strikes.
• In areas with frequent lightning activity, it is recommended to install a primary surge protector
(10/350 μs waveform) at the building’s main distribution panel, and a secondary surge protector (8/20
μs waveform) at the distribution cabinet or in front of the device to form a layered protection system.
• The surge protection components are single-use devices and may fail after exposure to high-energy
lightning strikes. Regular inspection is recommended, especially after lightning events.
• If the device is installed in open or elevated locations (such as rooftops), additional external lightning
protection measures (e.g., lightning rods) must be implemented.
0.2. Warning Marks
The warning labels on the system enclosure and within the system must be kept clean, legible, and clearly
identifiable.
0.3. Electrostatic Protection
1. Avoid allowing clothing or hands to come into contact with PCBs, electronic components, and conductive
surfaces of parts whenever possible. If handling of PCBs, components, or conductive parts is necessary,
proper anti-static precautions must be taken, such as wearing anti-static gloves or using anti-static bags.
Electrostatic discharge (ESD) may damage the equipment.
1.1. Standard
Protection rating complies with IP67.
RF performance complies with 3GPP standards.

3. RU4460 Access
3.1. Access via Debug Port
14 / 21
Check if ping IP 10.7.3.200 is successful.
Log in the RRU GUI via IP 10.7.3.200
Default user information (Account: admin Password: admin)
3.2. Access via BBU
Step 1: Preparation
15 / 21
a) Move file “iptables.sh” to BBU root directory.
Select SSH2, Port22, Account: root Password: root123
b) Script execution permission
# chmod 777 iptables.sh
c) Run the scripts
# ./iptables.sh
d) Run “rourte_config_5g_bbu” Script as administrator.
# route add 192.168.200.0 mask 255.255.255.0 192.168.5.100 -p
Note: in the script, the IP 192.168.5.100 should be modified.
For example, if the maintenance IP of BBU is 192.168.17.131, then need to change the script to:
#route add 192.168.200.0 mask 255.255.255.0 192.168.17.131 -p
e) Check if the script is successful
# route print
Step 2: BBU Side Configuration
Path: Home/Config/Service/RuManagement
16 / 21
Example: The RRU is connected to the BBU optical port 1, the Carrier0EaxcId should be set to 0.
Step 3: RRU Side Configuration
Path: Maintenance/Engineering/Connect/Option Port Selection
a) Select optical port
If the RRU is connected to the optical port 1 of accelerator card, optical port selection on RRU GUI should be
configured to 1.
Accelerator Card Port Optical port selection
1 1

3 3
4 4
b) Set Carrier 0 EAXC-ID and Carrier 0 bandsector-bitmask.
Carrier 0 EAXC-ID is 0 by default. The parameter should be configured based on the accelerator card port that the
RRU is connected to. Following is the mapping table. Path: Settings/Carrier Info/Carrier 0 configuration
17 / 21
Accelerator Card Port Carrier 0 EAXC-ID
1 0
2 1

Carrier 0 bandsector-bitmask should be changed to 15.
Step 4: visit RU4460 via BBU.
After finishing the above steps, it is reliable to visit RRU via BBU.
Accelerator Card Ports and RRU IPs’ mapping relationship is shown as follow.
Port IPs
1 192.168.200.10
2 192.168.200.20
3 192.168.200.30
4 192.168.200.40

Note:
a. The RRU script iptables.sh should be re-executed if accessing RRU from BBU fails after the RRU upgrade.
b. Repeat chapter 3.3.2 Step1 preparation once the BBU gets a power cycle.
