5. Press and release the On/Standby button on the bezel (FIGURE 2-2).
The system begins an orderly software system shutdown.
Note – Pressing and releasing the On/Standby button initiates an orderly software
shutdown. Pressing and holding the button for four seconds causes an immediate
hardware shutdown. Whenever possible, initiate an orderly shutdown. Forcing an
immediate hardware shutdown can corrupt the hard drive and cause loss of data.

This is the only way to remove power from the server. Electrical power is present
when the server is in Standby mode.
Caution – As long as the power input cables are connected, potentially hazardous
energy is present inside the server.

Powering Off the Server Remotely
To issue software commands, set up an alphanumeric terminal connection, a local
graphics monitor connection, ALOM connection, or a TIP connection to the Netra
240 server.
You can power off the system remotely either from the ok prompt or from the
ALOM sc> prompt.
Caution – Applications running on the Solaris platform can be adversely affected
by a poorly executed system shutdown. Ensure that you stop and exit applications.
Then shut down the operating system before powering off the system.
Powering Off the System From the ok Prompt
1. Before getting to the ok prompt, notify users that the system will be powered off.
