Chapter 1 Introduction to the Sun Fire X2100 Server 1-9
1.4.2 Powering Off the Server
1. Save your data and close any open applications.
2. Read all of the following power-off options before powering off the server:
■
Power off the server by using the operating system shutdown command or menu
option.
In most cases, this option powers off the operating system, then turns off the
power to the server.
■
If the server power is not turned off through the operating system command or
this command is not available, press and release the Power button (location
shown in
FIGURE 1-2
).
This option initiates an orderly shutdown of the operating system and powers off
the server.
Caution – Use one of the first two options whenever possible to avoid data loss.
■
If the server power is not turned off with one of the first two options, press and
hold the Power button for approximately 4 seconds.
This option shuts down the power to the server but does not initiate an orderly
shutdown of the system. This method could result in data loss.
If the preceding options fail to power off the server, see Section , “Troubleshooting”
on page 2-1 for more options.
After powering off the server, wait at least four seconds before powering on the
server again.
1.4.3 Power Interruptions
If the power to the system is interrupted for less than ten seconds, do the following
to ensure that the standby power is completely shut off:
1. Unplug the AC power cord from the server.
2. Wait ten or more seconds.
3. Plug the power AC cord into the server.
4. Power on the server.
