8.0 E4 System Troubleshooting
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.
8.2 E4 hardware indicators
8.2.1 Normal operation
These are the indications of normal operation.
8.2.2 System fault
A red SYSTEM STATUS LED indicates that the E4 received an
error from one of its many internal components. A red SYSTEM
STATUS LED after AC power is switched on may be caused by:
• A Power-On Self-Test failure
•A DSP error
•The DSP is offline
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.
