Chapter 2 Preparing to Service the System 21
Note – As soon as the input power cables are connected to the system, the ALOM
boots and displays its power-on self-test (POST) messages. Though the system
power is still off, the ALOM software is already monitoring the system. Regardless
of the system power state, as long as the power cords are connected and providing
standby power, the ALOM is monitoring the system.
3. Turn on power to any peripherals and external storage devices you have connected
to the server.
Read the documentation supplied with the device for specific instructions.

5. Set the rotary switch to the Normal or Diagnostics position (
TABLE 2-2
and
FIGURE 2-3
).
6. Press the On/Standby button.
Verbose POST output is immediately displayed to the system console if diagnostics
are enabled at power-on. The system console is directed to the serial and network
management ports.
The system can take anywhere from 30 seconds to 5 minutes before text messages
appear on the system monitor (if one is attached) or the system prompt appears on
an attached terminal. The time depends on the system configuration (number of
CPUs, memory modules, PCI cards, and console configuration) and the level of
power-on self-test (POST) and OpenBoot Diagnostics tests being performed. The
System Activity LED lights when the server is running under control of the Solaris
platform.
