What to Do

1. Turn on power to any peripherals and external storage devices.

   Read the documentation supplied with the device for specific instructions.

2. Turn on power to the monitor or terminal.

   A terminal or monitor is required for viewing system messages. For setup instructions, see "How to Attach an Alphanumeric Terminal" or "How to Configure a Local Graphics Console".

3. Turn the front panel keyswitch to the Power-on position or to the Diagnostics position.

   See "About the Status and Control Panel".

   Use the Diagnostics position to run POST and OpenBoot Diagnostic tests to verify that the system functions correctly with the new part(s) you have just installed. For additional information, see Chapter 12, Diagnostics and Troubleshooting.

4. When the system banner is displayed on the monitor or terminal, immediately enter the Stop-a sequence on the Sun keyboard or press the Break key on the terminal keyboard.

   The system banner contains the Ethernet address and host ID. To enter the Stop-a sequence, hold down the Stop key and press the a key.

   Note -

   The system may take anywhere from 30 seconds to two minutes before the system banner appears. This time depends on the level of power-on self-test diagnostics being performed.

5. When the ok prompt is displayed, enter the following command:

   ---

   ok boot -r

   This command rebuilds the device trees for the system, incorporating any newly installed options. After a device has been added to a device tree, it can be recognized by the system. After the reconfiguration reboot has successfully completed, the system prompt should be displayed.

   Caution -

   Never move the system when system power is on. Movement can cause catastrophic disk drive failure. Always power off the system before moving it.
