GX450 Possibly Bricked - Help


I have a GX450 that does not seem to be working.
When I power it up Power, Activity and Signal lights are all solid red.
I can not seem to communicate by ethernet, usb or serial as described in instructions.
Ethernet LED’s do not light up when connected
Usb device is not detected by PC.

Hoping to repair if necessary and hopefully get it working.

Any help would be appreciated.
