Stopping the System
Attention: When shutting down your system to install options, shut down all
applications first and then shut down the operating system. The system power turns off
and the system goes into standby mode when the operating system is shut down.
Before removing power from the system, ensure that the shutdown process is complete.
Failure to do so can result in the loss of data. Some option-installation procedures do
not require the system to be stopped for installation. The option-installation procedures
in this chapter will direct you here if stopping the system is required.
1. Log in to the system as root user.
2. Ask the customer to stop all applications that are running on the system.
3. At a command line, type shutdown to stop the operating system.
4. After you shut down the operating system, set the power switches of any attached
devices to Off.
Starting the System
To power on the system, perform the following steps in sequence.
1. On a Model 6C4, open the front rack door.
On a Model 6E4, open the bezel door.
2. Look for the OK in the operator panel. The OK indicates that the system is in standby
mode.
3. Press the power-on button on the operator panel.

The power LED on the operator panel starts blinking at a fast rate. 9xxx checkpoints
appear in the operator panel display.
When the power-on sequence is complete, the power LED on the operator panel stops
blinking and remains on.
