To reset a MOXA network device to factory-default, we can login the device via web console, telnet console or serial console.
Web Console
telnet/SSH/serial console, menu mode
telnet/SSH/serial console, CLI mode
However, if we forgot the password, we're not able to reset factory-default via console since they all need to login first. There is a reset button in some models, such as IKS/ICS rack switches, however, there is not in other models, such as EDS-xxxA or EDS-xxxE.
To reset these early models without RMA, you can use SNMP since the SNMP is default enabled in these early models.
To confirm if the SNMP is enabled by default, you can check official manual.
To use the SNMP, you need to download the SNMP MIB for your device first.
SNMP MIB for specific model
Be caution, some PoE models are not using the same MIB file with non-PoE model.
MIBs are different from TN-4516A (4th) and TN-4516A-PoE (1st)
To use SNMP reset a devices, we need a SNMP tool first, below I'm going to use iReasoning MIB Browser.
You can download it from official site for free: https://ireasoning.com/mibbrowser.shtml
After install MIB browser, "File" > "Load MIBs"
Choose you MIB file and then "Open"
Input your device IP, click "Advanced...", input the SNMP communities in the prompt window.
By default, Read Community is "public" and Read/Write Community is "private".
Then click "OK".
Extend the MIB tree, and go to "private" -> "enterprises" -> "moxa" -> "industrialEthernet" -> YOUR DEVICE MODEL -> "swMgmt"
You can try to double-click "switchModel" to see if returned value is correct or not.
Find "enableFactoryDefault" under swMgmt, click it, then choose "Set" from the drop-down list by the "Operation:".
Set the value to "1" in the prompt window.
Finally, click "Ok" to start the reset.
