Halting the System
Before you remove a replaceable part, you must halt the system according to the
following procedure.
Caution - When the operating system or any other stand-alone program has already
booted, do not use the Stop(L1)-a keys to halt the system. Using
the Stop(L1)-a keys to abort program execution can cause damage to data files.
1. Save any files you are presently editing.
2. Quit from any applications that will lose information when the system halts.
See the Sun System User’s Guide for more information about ending a work
session.
