Chapter 2 System Setup 43
How to Power On the System With
Full Diagnostics Enabled
Before You Begin
You need the system key to perform this procedure.
If a local graphics console or ASCII terminal is not already connected to the system,
you need to install one before continuing the startup procedure. For information,
see:
■ “How to Attach an Alphanumeric (ASCII) Terminal” on page 34
■ “How to Configure a Local Graphics Console” on page 36
Note – If you have just installed an internal or external storage device other than an
FC-AL drive or a USB device, or any new part that plugs in to the main logic board,
only restart the system to bring it to the operating environment level after
performing a reconfiguration boot.
The operating system cannot recognize newly added devices or parts until you have
performed a reconfiguration boot. The new boot will add any new devices to the
factory-configured device tree. For more information, see “How to Initiate a
Reconfiguration Boot” on page 136.
For more complete interpretation of the diagnostic output from this procedure,
consult “About Diagnostic Tools” on page 160.
What to Do
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. For
more information, see “How to Power Off the System” on page 61.
Caution – Before you power on the system, make sure that the top cover is properly
installed. See the Sun Fire 280R Server Service Manual for more information.
