After using the device, the user may change the default user name and password. If you forget the password of user root, please perform the following methods. Method 2 is recommended.
Method 1: Load the empty database matched the device again through DoS. After restarting the device, log in to the system by using the default root password admin (OLT) or mduadmin (MDU). This method will lead to loss of data configurations and the user needs to configure the data again.
Method 2: Modify the configuration file using the U2000.
1. On the U2000, choose Administration > NE Security Management > LCT User Management from the main menu.
2. On the LCT User Management tab page, select NE User and then Device Type. Select the desired device name from the Device Name column and user name from the Name column. In the displayed dialog box, choose Set Password to set the new password.
This method does not require a device restart or services are not interrupted.
Method 3: If the device is managed by the NMS, modify the configuration file on the NMS as follows:
1. Back up the configuration file of the device on the NMS.
2. Open the configuration file and find out the record of changing the root password, as shown in boldface in the following display.
