Hello,
Please find below how you can connect to rtn980A with web lct.
Connecting the Web LCT to the Equipment
Properly connecting the Web LCT to the equipment is a prerequisite for configuring commissioning data for the equipment.
Prerequisites
Tools, Equipment, and Materials
Web LCT (Win7 operating system)
Background Information
This section describes how to connect the OptiX RTN 380A to the Web LCT through WLAN,as shown in Figure 1. If the WLAN module is abnormal, connect the OptiX RTN 380A to the Web LCT through the Ethernet network management interface or through the Ethernet network management interface of an NE that communicates with the OptiX RTN 380A through the DCN,as shown in Figure 2 and 3. The IP address of the Ethernet ports on the computer that houses the Web LCT must be in the same network segment as the NE IP address. The two IP addresses must be different.
Figure 1 Ways for connecting the Web LCT to an OptiX RTN 380A

NOTE:
If a site has several cascaded OptiX RTN 380As, connect the laptop to only one of the OptiX RTN 380As. Other OptiX RTN 380As can be connected through the internal DCN. If the a GE electrical interface is set as the NMS interface, it can be connected to the Web LCT.
Use either a crossover cable or a straight-through cable to connect the laptop to the OptiX RTN 380A. For the wire sequences of crossover cables and straight-through cables, see Cable in the OptiX RTN 380A Microwave Transmission System Product Description.
Procedure
Start the laptop and log in to the operating system.
Use the Wi-Fi Connection tool delivered with the Web LCT to set up a Wi-Fi connection between the laptop and NE.
The default SSID is EMn-The last six digits of a MAC address in hexadecimal format-NE ID.
Default password: Modify_123.
If the WLAN Connection tool does not find the SSID of the NE, perform the following operations:
Generally, it takes about 20s to set up connection through WLAN, please be patient.
If a WLAN connection fails to be set up, check whether:
Check whether there is a block between the laptop and the NE.
Check whether the distance between the laptop and NE is longer than the typical WLAN transmission distance. (The typical transmission distance between the WLAN module and laptop is 30m. An external WLAN network adapter can be installed on the laptop to extend the typical transmission distance to 70 m.)
If the distance between the laptop and NE is shorter than the typical WLAN transmission distance, view the status of the WLAN indicator in the maintenance compartment. If the WLAN indicator is red (indicating the abnormal state), replace the WLAN module or connect the laptop to the NMS port in the maintenance compartment to check the WLAN configuration.
The connection password is correct.
The IP address is automatically allocated.
Another laptop is connected to the NE though WLAN. Only one device can access an NE through WLAN at a time. If another device needs to access the NE, it is recommended that you use the WLAN Connection tool to disconnect the first device and then access the second device. The disconnection method is similar to the connection method.
Access the Wi-Fi Connection tool directory (such as WebLCT\weblct\tools\wificonn) and run WifiConnection.exe.
Select the SSID of the NE to set up a WLAN connection.

NOTE:
After the Web LCT and the OptiX RTN 380A are properly connected, the indicator at the Ethernet port of the laptop is steady green. A message is displayed indicating that the network has established a local connection if the operating system has been configured to do so.
After the WLAN connection is set up successfully, double-click the Start Web LCT icon on the desktop.
The system displays the USER LOGIN window of the Web LCT.

Set User Name, Password, and Verification Code, and click Login.
NOTE:
At the first login to the Web LCT, change the password as prompted.
If the entered user name and password are correct, the NE List page is displayed.

User Name: admin
Password: Changeme_123
Follow-up Procedure
If you cannot access the USER LOGIN window or the NE List page, configure the Internet Explorer using the following method:
