8.1 Introduction

This section provides troubleshooting guidelines to use for solv-

ing any problems you may encounter while installing and servic-

8.2 FreeSpace 4400 hardware

indicators

8.2.1 Normal operation

These ar e the indication s of normal operation.

8.2.2 System fault

A red SYSTEM STATUS LED indicates that the FreeSpace 4400

rece ived an error fr om 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, cycl e 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.
