system boots up.

To add AC power, connect the power cord plug to each AC power connector. Make sure that the power
cord is secure (as shown in the following illustration).
CAUTION: Ensure that you correctly install the PSU. When correctly installed, the AC power
connector is on the left side of the PSU and the status LED is at the top of the PSU (as shown in
the following illustration).
As soon as the cable is connected between the S4810–ON and the power source, the system is
powered-up; there is no on/off switch.
