The UpdateXpress program
The UpdateXpress program is available for most System x servers and optional
devices. It detects supported and installed device drivers and firmware in the server
and installs available updates. You can download the UpdateXpress program from
the Web at no additional cost, or you can purchase it on a CD. To download the
program or purchase the CD, go to http://www.ibm.com/servers/eserver/xseries/
systems_management/ibm_director/extensions/xpress.html.
Additional information
about UpdateXpress is available from the System x and xSeries Tools Center at

Power-on LED: When this LED is lit and not flashing, it indicates that the server is
turned on. When this LED is flashing, it indicates that the server is turned off and
still connected to an ac power source. When this LED is off, it indicates that ac
power is not present, or the power supply or the LED itself has failed.
Note: If this LED is off, it does not mean that there is no electrical power in the
server. The LED might be burned out. To remove all electrical power from the
server, you must disconnect the power cord from the electrical outlet.
Power-control button: Press this button to turn the server on and off manually. A
power-control-button shield comes installed around the button to prevent the server
from being turned off accidentally. You can remove this disk-shaped shield if you
prefer.
Reset button: Press this button to reset the server and run the power-on self-test
(POST). You might have to use a pen or the end of a straightened paper clip to
press the button.
Hard disk drive activity LED: When this LED is flashing, it indicates that a hard
disk drive is in use.
