Pretty much depends on what you wanna do on this system.
The last things I made on t1000 server were :
shell change, root pass change, new sshd options, allowed/denied services, one user added, new path credentials added + export, added extra disk, configured ALOM, verified its functionality, edit of /etc/profile, bash_profile, ulimits, new start-up scripts, stopped unused daemons, echo-ed new TCP / kernel parameters, and many more
