Why I can not found the WGT-705A after slide into the Media Chassis WMC-1600R?

Please check if the firmware of the WMC-1600R is version 1.14 or above.
If the firmware version is older than version 1.14, WMC-1600R will not contains the record of WGT-705A and will not shows the information at its console interface or Web interface. Please upgrade the firmware to the latest version for device supporting.
