Issue Description

On Huawei MA5608T+H808EPSD, the system prompts that the board does not support this operation when confirming an automatically discovered ONT.

Alarm Information

0x023100ed Board Software Automatic Expansion Failure

Handling Process

1. Run the display board command to check whether the status of each board is normal.

 

2. Run the display alarm active all command to query the alarms. The command output shows the 0x023100ed Board Software Automatic Expansion Failure alarm on the H808EPSD board.

 

3. Run the display io-packetfile information command, output shows that there is no I/O package of H808EPSD.

 

4. Run the display version command, the output shows that the version of the MCUD control board is V800R017C00 and the software app version of the H808EPSD board is 2013. The version difference is large.

 

5. Load the combined package of the V800R017C00 version and add the I/O package of the H808EPSD board. The issue is solved.

Root Cause

The H808EPSD board software is not upgraded to the latest version. As a result, the board status is normal, but the board cannot carry services or the services are limited.

Solution

Upgrade the software of the H808EPSD board to the latest version.

Suggestions

When a user interface board is inserted, the version information about the board is reported to the system. If the version of the board software is inconsistent with that of the board software stored in the flash of the control board, the system automatically loads the software. If the automatic loading fails, the system generates the alarm 0x2420a003 Automatic Loading Failure. Impact of the alarm on the system: The board software of the interface board is not upgraded to the latest version. As a result, the board cannot carry services or the services are limited.

How to Do If the Root Password of a Device Is Lost?

After using the device, the user may change the default user name and password. If you forget the password of user root, 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 (Huawei 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.

  3. Delete the boldface part and then save the configuration file.
  4. Load the modified configuration file to the system through the NMS and activate the configuration file.
  5. Log in to the device by using the default root password admin (OLT like Huawei MA5608T) or mduadmin (MDU).

What is the System Architecture of Huawei GPON OLT?

Huawei MA5608T/MA5603T/MA5800T uses the system architecture containing three modules: M1, M2, and M3.

• The M1 service port module provides various service access ports, such as PON, P2P, POTS, and xDSL service ports.
• The M2 core processing module implements CPU processing, Ethernet switching, and service processing.
• The M3 uplink port module transmits service flows upstream to network-side devices.

Figure 1 System architecture

In the preceding figure:

• The M1 service port module and M3 uplink port module connect to different boards. For details of working principles of each module, see board description in the Hardware Description.
• For details of service flow directions in the M1 service port module, see board working principles in the Hardware Description.
• The service flows processed by the M2 core processing module are classified into two types: One type of service flows are transmitted upstream after they are processed by the Ethernet switching module and the M3 uplink port module; the other type of service flows are transmitted upstream after they are processed by the Ethernet switching module, service processing module, and then Ethernet switching module again.
