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.
