1: Operation Procedures
A console is defined as a connection to the system (to the administrative server) that provides
administrative access to the cluster. SGI offers a rackmounted flat panel console option that
attaches to the administrative node’s video, keyboard and mouse connectors.
The rackmounted console option is always installed in the air-cooled rack used for administrative,
RLC and service node units.
A console can also be a LAN-attached personal computer, laptop or workstation (RJ45 Ethernet
connection). Serial-over-LAN is enabled by default on the administrative controller server and
normal output through the RS-232 port is disabled. Check with your service representative if use
of an RS-232 terminal is required for your system.
The flat panel rackmount or other optional VGA console connects to the administration
controller’s video (VGA) and USB connectors on the back of the system (see Figure 1-2).

Powering the System On and Off
This section explains how to power on and power off individual rack units, or your entire SGI ICE
XA system, as follows:
• “Preparing to Power On” on page 5
• “Powering On and Off” on page 8
Entering commands from a system console, you can power on and power off individual blade
enclosures, blade-based nodes, and stand-alone servers, or the entire system.
