Chassis LEDs, Buttons and Connectors
There are two push buttons and several LEDs on the right hand side of the SGI 1200
server front panel. The following sections provide information about the buttons and
LEDs on the front and back panel, and information about error conditions that the LEDs
can indicate. The information in this section can help you make a quick visual inspection
of the status of the hard drives, network connections and internal components of your
SGI 1200 server.
If the amber Global Failure LED that you can view through the front cover does light, you
can use the information in this section, and Chapter 5 to troubleshoot the failure source.

Front AC Power Push Button
Pressing this button powers on the SGI 1200 server. If you decide that you don’t want to
power up the SGI 1200 server, press the button again to immediately shut down the
system. The blue LED will blink briefly and the server shuts down before the BIOS or
operating system are initialized.
When the SGI 1200 server is operating, holding this button for five seconds issues a
shutdown
command to the system.
