8.1 Introduction
This section provides troubleshooting guidelines to use for solv- ing any problems you may encounter while installing and servic- ing E4 systems.

To determine the severity of the error, cycle the E4 unit power off and back on again. If the SYSTEM STATUS indicator is now off, the E4 system has logged an error, but is still operational.
When you check the error log using the FreeSpace® Installer™ software you can identify the cause of the error, and determine an appropriate solution.
