Troubleshooting

How to get the expansion module’s syslog

Press the “left button” of the expansion button 3 times in succession + press the “right button” of the expansion board 1 time and hold for 15 seconds, enter the menu interface of the expansion board.

Check the expansion module’s IP via the expansion module’s menu interface.

Directly connect your computer to the expansion module’s Download Link port, and set a static IP for the computer which is under the same subnet as the expansion module.

For example, the expansion module’s IP address is 172.20.0.4/24, then set the computer’s IP address as 172.20.0.100/24.

Visit the expansion module’s webpage, enter Management → Configuration, download syslog.

The Expansion Module Shows Network Down

1. Check if the expansion module is connected correctly (the right way to connect should be: uplink port of the expansion module is connected to the phone’s PC port; or uplink port of the expansion module is connected to the Download Link port of the previous expansion module).

1. Check if the phone’s PC port, or the Download Link of the previous expansion module is normal (can use an expansion module that has been verified to be normal to test the connection).
