6. Press and release the On/Standby button to power on the system (
FIGURE 2-2
).
The power supply Power OK LEDs light when power is applied to the system.
Verbose (POST) output is immediately displayed to the system console if diagnostics
are enabled at power-on, and the system console is directed to the serial and
network management ports.
The system can take anywhere from 30 seconds to 20 minutes before text messages
appear on the system monitor (if one is attached) or the system prompt appears on
an attached terminal. This time depends on the system configuration (number of
CPUs, memory modules, PCI cards, and console configuration) and the level of
POST and OpenBoot Diagnostics tests being performed. The System Activity LED
lights when the server is running under control of the Solaris OS.
7. Turn the rotary switch to the Locked position (
FIGURE 2-2

This prevents anyone from accidentally powering off the system.
