This seems likely to be a hardware issue with the switch then.
One last check, are these combo ports that can go either ge or xe?
See if you have a configuration or a recognized port in the ge version.
show interfaces terse ge-0/1/2
show configuration interfaces ge-0/1/2
Assuming these are also not present then your hardware has failed. You will need to open a JTAC ticket on the support site to verify and get an RMA replacement.
