NOTE:
System power does not shut off completely with the power button. Standby removes power from most of
the electronics and the hard drives, but portions of the power supply and some internal circuitry remain
active. To remove the power completely, disconnect all power cords from the device. For instructions,
see “ Powering off the MSA1510i ” on page 38.
