Our ZF7372 worked well for 72 hours or so. Magically, it was "disconnected" per our console on the ZD3000.
Power light is solid green and the DIR light is blinking green. NO other lights 30 seconds after reboot. Just power light is solid green and the DIR light is blinking green.
I could not find any doc that explains the standard LEDs on any current ZF units.
Anyone?
