8.3.2 Hardware configuration

The FreeSpace 4400 system hardware version numbers appear
at the top of the Error Log listing. These are the version numbers
of the software installed in the FreeSpace 4400 hardware at the
time of manufacture. These version numbers do not pertain to the
FreeSpace 4400 Installer™ software installed on your PC.

8.3.3 Power-on self-test results

The power-on-self test (POST) results are only displayed when an
error has occurred. The POST test checks the basic operation of
the FreeSpace 4400 hardware to determine if it is capable of
properly performing audio processing and amplification. During
the POST test, five major components of the hardware are
tested.
4400 System Troubleshooting
®
® FreeSpace 4400 Error Log
• Host controller – The host controller monitors and controls the
operation of the FreeSpace 4400 hardware. A host controller
failure will cause the message, "Power-on self-test incomplete"
to appear in the host controller test section. The failure type for
a host controller is an SRAM address failure. If this occurs,
contact your local Bose representative or visit pro.Bose.com.
• Flash memory test – The flash memory contains the configu-
ration, design file, and system event schedule. A flash failure
will cause the message, "Power-on sel-test incomplete" to
appear in the host controller flash test section. If this occurs,
contact your local Bose representative or visit pro.Bose.com.
• Peripheral controller – The peripheral controller monitors con-
tact closures, front panel connections and user interface con-
nections for incoming event messages. Any failures in these
areas will cause the message, "Power-on self-test incomplete"
to appear in the peripheral controller flash test section. If a 12C,
or code failure occurs, contact your local Bose representative or
visit pro.Bose.com. If a user interface failure occurs, check the
user interface wiring for shorts.
• DSP test – The DSP performs all signal processing and routing
functions. If a DSP error occurs, contact your local Bose repre-
sentative or visit pro.Bose.com.
• Upper and lower amplifier test – The upper and lower ampli-
fier test determines if the amplifiers are operating properly. An
amplifier failure will cause the message, "Power-on self-test
incomplete" to appear in the upper or lower amplifier section of
the POST test results. If a 12C, or code failure occurs, contact
your local Bose representative or visit pro.Bose.com. Additional
details on the exact cause of an amplifier failure can be found
in the amplifier section of the Error Log.
