Chapter 2 Setting Up the System 41
3. Insert the system key into the front panel keyswitch and turn the keyswitch to the
Normal position.
4. Press the Power button to the left of the keyswitch to power on the system.
5. When the diagnostic tests are completed, the system banner is displayed on the
system console followed by the ok prompt.
The system banner contains the Ethernet address and host ID.
Note – The system may take up to 30 minutes or longer to run diagnostic tests and
display status messages before the ok prompt appears on the system console. The
time depends on the system configuration (number of processors, memory modules,
and PCI cards) and the standard default configuration of the OpenBoot variables,
which by default are set at diag-level=max and verbosity=normal.To
customize the standard configuration after initial power on, see the OpenBoot PROM
Enhancements for Diagnostic Operation guide, which is included on the Sun Fire V890
Documentation CD.
6. At the ok prompt, type:
The env-on command re-enables the OpenBoot environmental monitor, which may
have been disabled as a result of the abort key sequence. The boot -r command
rebuilds the device tree for the system, incorporating any newly installed options so
that the operating system will recognize them.
