4.1.2 Troubleshooting Using the Embedded
Management System
If you have looked over and tried the things mentioned in
still have not resolved the problem, there are some additional tools and
techniques that can be used. The embedded Management System is a
good source of information that may be used remotely to provide pre-
liminary diagnostic information, or may even provide a path to cor-
recting the problem.
