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.
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. In certain limited cases, a dumb (RS-232)
terminal could be used to communicate directly with the administrative server. This connection is
typically used for service purposes or for system console access in smaller systems, or where an
external ethernet connection is not used or available. 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 and keyboard/mouse connectors as shown in Figure 1-2.
