Sun Microsystems 280R How to Power On the System With Full Diagnostics Enabled, Before You Begin

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.
