Can I install a MGB-SX or other non-wide temperature SFP module into the SFP 

slot of the industrial managed switch?

Yes. However, the MGB-SX and other non-wide temperature SFP modules cannot 

operate under the wide temperature range of -40 to 75°C. We recommend using an IFS 

wide temperature SFP module for the industrial managed switch.

If an IP address needs to be changed or an admin password is forgotten:

To reset the IP address to the default IP address “192.168.0.100” or reset the password 

to default value, press the hardware reset button at the front panel for approximately 10

seconds. After the device is rebooted, you can log in to the management web interface 

within the same subnet of 192.168.0.xx.
