Power On the Server

If you removed power from the server during maintenance, use the following procedure to reapply main power for all server components.

1. Verify that the power cords are connected to the server and that standby power is on.

   • Shortly after AC power cords are plugged into the server, the SP OK indicator blinks as the service processor boots.

   • The SP OK indicator is illuminated solid green when the service processor has successfully booted.

   • After the service processor has booted, the System OK indicator on the front panel begins flashing slowly, indicating that the host is in standby power mode.

2. Press and release the recessed Power button on the server front panel.

   • When full power is applied to the server, the System OK indicator begins to blink more quickly as the system begins the boot process.

   • During the boot process, the server initiates a power-on self-test (POST) which might take several minutes to complete.

   • Once the host boot process is complete, the System OK indicator and lights solidly.
