When an SRX is in cluster mode certain configurations and status can cause interfaces to go inactive. And on some models optical ports with multiple option settings will not show up unless the optic is present. But neither of these is likley to show zero interfaces on a new SRX.
Look for alarms
show chassis alarms
And check the hardware status of the fpc
show chassis hardware
If the fpc is offline add extensive to get more information. You could also try a factory reset and reboot.
