If you shut down the Netra 150 server using the Netra HTML interface (found under System Administration:Restart and Shutdown), this does not remove power from the Netra 150 server. To completely power off the server, the power switch located on the back of the Netra 150 server must be used. This is the switch for the server. Turning this switch to the off position will actually turn off the power to the server.
This switch is only to be used to power off the server to allow new hardware to be installed or replaced. Always shutdown the server gracefully before powering off the server.
