8.0 FreeSpace ® 4400 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 FreeSpace 4400 systems.
8.2 FreeSpace 4400 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 FreeSpace 4400
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 FreeSpace 4400
system power off and back on again. If the SYSTEM STATUS
indicator is now off, the FreeSpace 4400 system has logged an
error, but is still operational.
When you check the error log using the FreeSpace ® 4400
Installer™ software you can identify the cause of the error, and
determine an appropriate solution.
