MCU Displayed as Offline on the SMC2.0

Hello, guys!

Good day to you!

This topic describes the solution to MCU displayed as offline on the SMC2.0.

Symptom

After an MCU is added to the SMC2.0, it is displayed as offline.

Possible Causes

• The port settings on the SMC2.0 and MCU are different.

• The connection modes or passwords set on the MCU and SMC2.0 are different.

Procedure

1. Check whether the MCU connection type is set to SMC2.0/IMS.

   1. Log in to the MCU web interface and choose Settings > System > Connection Management.
      

   2. Check whether the value of Connection type is SMC2.0/IMS.
      

2. Check whether the same port is specified on the SMC2.0 and MCU for their connection.

   1. Log in to the MCU web interface, choose Settings > System > Connection Management, and check the value of Port.

   2. Log in to the SMC2.0 web interface, select the MCU you want to check, click Edit MCU, and change the value of Port to the port number that you see in the previous step.

   3. Click Save and check whether the MCU gets online. If it is still offline, repeat 3.
      

3. Check whether the same connection mode and password are specified on the SMC2.0 and MCU for their connection.
   

   1. Log in to the MCU web interface and choose Settings > System > Connection Management.
      

   2. Check the values of Connection mode and Connection password.

   3. Log in to the SMC2.0 web interface, select the MCU you want to check, and click Edit MCU.
      

   4. Set Connection mode and Connection password to the values you have obtained in step 2.
