2.1 Environmental and safety requirements
Environmental and safety requirements for Foxconn RPQN O-RU hardware installation.
Warning: Electric Shock.
Please notice that the RF ports should be connected to a 50 Ω load (for example, feeder with an antenna) before
powering on the RPQN O-RU. The plastic caps delivered can provide electric shock protection in case RPQN O-RU is
unintentionally power on. Please keep plastic caps remained in place for the unused RF ports.
Warning: Hot parts.
To avoid the risk of hot parts, please use the RPQN O-RU with caution, and wait at least 30 minutes before handling
the RPQN O-RU after powering off.
Only trained and qualified personnel are recommended to install, operate, maintain or handle the RPQN
O-ORU, and please carefully read the safety information applicable to this product.
Only install RPQN O-RU in a restricted access location, and meet the minimum requirements of RF exposure
compliance distance.

4 Operating instruction
4.1 Normal operation
4.1.1 PTP 1588v2 clock source setting
Before starting to use a RPQN O-RU, please set your PTP 1588v2 GM or BC correctly to match the design of
RPQN O-RU. In the following example, a Qulsar QG2 GM is used. The following pictures referenced from
Qulsar’s user manual and the setting in the pictures may not be matched to RPQN O-RU’s design.
■Step 1: Get or set the IP address of the port the RPQN O-RU to be connected (GM or BC). For
example, the IP address of those two ports (GM/BC and RPQN O-RU) are 10.0.1.179 and
192.168.16.150, respectively. If the port does not support DHCP, please remember to
configure a proper IP with the same sub-net for RPQN O-RU later. Besides, RPQN O-RU does
not support VLAN in PTP. Please disable the VLAN in GM/BC.
Figure 14 Get/Set IP address of PTP Clock Source GM or BC
■Step 2: Set GM/BC as an Ordinary clock, OFF the “Two Step” and set or get the domain
number. The suggested value is 44. If you choose other value, please set the same value in
RPQN O-RU in the later step.

■Step 3: Set the PTP network protocol to IPv4 (UDP) and delay mechanism to End-to-End.
Suggest to set “Sync Interval”, “Delay Request Interval” to 0, “Announce Interval” to 3 and
“Announce Receipt Timeout to 3.
NOTE: If the maximum announce interval supported in your GM is 0, please set the
announce interval to 0 instead of 3

4.1.3 RPQN O-RU setting
■Step 1: Use a Micro-USB cable to connect to a RPQN O-RU from your PC
■Step 2: Start the tool “Device Manager” in your PC and check the COM port number of
RPQN O-RU. For example, there is a USB Serial Port with COM port number 19 after RPQN
O-RU is connected.
Figure 18 Example of COM Port in Device Manager
■Step 3: Start a terminal software such as “PuTTY” on your PC and select “Serial” protocol.
The baud rate is 115200 and other configurations are shown below.
Figure 19 Baud Rate Setting of Serial Connection
■Step 4: Power on the RPQN O-RU and it would run initial boot-up process automatically.

Please DO NOT press any key when a down-count counter is shown in the boot-up process.
After the following message is shown, the initial boot-up process is done correctly.
Figure 20 Example of Boot-up Process Success
■Step 5: Modify related configuration via:
◆Configuration file: /home/root/sdcard/RRHconfig_xran.xml, please reference step 5.1.
◆M-plane: please reference step 5.2. (The firmware version should > v1.0.3q.432)
■Step 5.1: In the terminal software window, use vi command to edit the configuration file,
/home/root/sdcard/RRHconfig_xran.xml. Please keep the format the same as the default.
For example, if a value is set in hexadecimal format, use the same format after changing to a
different value. Besides, if a space character or a comma character is used, please do not
remove them.
◆Set:
1. BBU’s MAC address in the field “RRH_DST_MAC_ADDR”.
2. RU’s MAC address in the field “RRH_SRC_MAC_ADDR”.
Figure 21 Set BBU MAC Address to Be Connected with RPQN O-RU
◆Set the VLAN ID for C-plane and U-plane, respectively.
The default value is 0x0001 and 0x0002.

Figure 22 Set VLAN Tag ID for C/U-Plane
◆Set the LO frequency of RPQN O-RU (in kHz).
1. RXXN-4100: 2593000 (2496~2690MHz)
2. RXXN-7800: 3352260 (3300~3600MHz)
3. RXXN-7801: 3749700 (3700~3800MHz)
4. RXXN-7901: 4849860 (4800~4900MHz)
Figure 23 Set LO Frequency
◆Set the GM’s IP address and domain number.
Figure 24 Set PTP Clock Source IP Address to be Connected with RPQN O-RU
For other fields in the RRHconfig_xran.xml, you can keep it in default.
■Step 5.2: To connect to the NETCONF Server of RRH when M-plane is activated from a
NETCONF client, please use “root/root” to login for username and password respectively.
For example, we use a NETCONF Client named “yangcli” to connect to NETCONF server.
◆a. Set BBU’s MAC address from NETCONF Client with xpath
“/processing-elements/ru-elements/transport-flow/eth-flow/o-du-mac-address” with
the name“PE0” of ru-element’s name in processing elements.
◆b. Set the VLAN ID for C-plane and U-plane, respectively. The default value is 1 and 2.
To modify the VLAN ID of C-plane and U-plane, the xpath is
“/interfaces/interface/vlan-id” and the name of interface is “iC” and “iU” for C-plane
and U-plane.
There is an xpath “/processing-elements/ru-elements/transport-flow/eth-flow/vlan-id”
needs to modified if VLAN ID of interface “iU” changed. It must be aligned to the VLAN

ID of U-plane.
◆c. Set the LO frequency of RRH (in Hz). The xpath is
“/user-plane-configuration/tx-array-carriers/center-of-channel-bandwidth” with the
name “TX-Ca0” of tx-array-carries.
◆
19
This confidential document is the property of Foxconn and must not be copied or circulated without permission.

Foxconn RPQN O-RU Installation and Operating Guide HON HAI Technology Group
HON LIN TECHNOLOGY CO., LTD.
◆d. Set the GM’s IP address and domain number, the xpath are
“/sync/ptp-config/g-8275-2-config/master-ip-configuration/ip-address” and
“/sync/ptp-config/domain-number”. To set
“/sync/ptp-config/g-8275-2-config/master-ip-configuration/ip-address” with NETCONF
Client, the key of xpath
“/sync/ptp-config/g-8275-2-config/master-ip-configuration/local-priority” must set as
“128” as default.
To let the RRH applies the new configurations, please reboot the RRH.
■Step 6: Check IP related configuration via:
◆IP Configuration: “ifconfig” command to check, please reference step 6.1.
◆M-plane: please reference step 6.2. (The firmware version should > v1.0.3q.432)
■Step 6.1: Use a network cable to connect RPQN O-RU and GM/BC you use. If the GM/BC
supports DHCP server, RPQN O-RU should get an IP address after connecting. You can use
“ifconfig” command to check. If the GM/BC does not support DHCP server, please use
“ifconfig eth0 xxx.xxx.xxx.xxx netmask 255.255.255.0” to configure the RPQN O-RU’s IP
address. Please make sure to use the same sub-net number as the GM/BC uses.
■Step 6.2: Use a network cable to connect RRH and GM or BC you use. If the GM supports
DHCP, RRH should get an IP after connecting. When the M-plane is activated, you can use
“./set_oam_mode -e” command to enable DHCP. If the GM does not support DHCP, please
use “./set_oam_mode -e IP_ADDR 255.255.0.0 GATEWAY_IP_ADDR” to configure the RRH’s
IP. Please make sure to use the same sub-net number as the GM uses. Then please reboot
the RRH.
