19-002 BIOS/Self-Test Fault RAP
NOTE: There are two configurations of the IDFE for this machine. They are identifiable by the
Product Code on the ID tag and by the number of Diagnostic LEDs. Early versions have 5
LEDs and are labeled Product Code GL2. Later versions have 6 LEDs and are labeled Product
Code MFY. This RAP applies generically to both. Where differences between the units exist,
the applicable information is followed by the product code for the specific IDFE.
A 19-002 fault is a BIOS-level hard fault, that was detected at power up. A continuously ener-
gized red Failure LED indicates that a 19-002 fault has occurred.
Initial Actions
• Refer to BSD 16.1.
NOTE: Before replacing any of the parts shown in BSD 16.1, ensure that the connectors
for the parts are correctly seated.
• Inspect and re-seat DC wiring harness connector P/J899 ( Flag 1 ). This connector sup-
plies DC power to the IDFE.
• Refer to OF19-1 IDFE Fault Entry Rap, Figure 1 (GL2) or Figure 2 (MFY), Diagnostic
LEDs and their locations.
Procedure
PO/PO the machine ( GP 8 IDFE Power OFF/Power ON (PO/PO) ).
NOTE: Check the red Failure LED 70-180 seconds (GL2) or 60 - 80 seconds (MFY) after PO/
PO.
The red Failure LED is continuously energized after 70-180 seconds (GL2) or 60 - 80 sec-
onds (MFY) s after power up.

If an intermittent fault is suspected, perform the following:
•
Go to Flag 1 and Flag 2 of BSD 16.1, and check for loose connections.
• Check that the Memory DIMMs are correctly installed and are not damaged ( REP
19.3 ).
• Replace the Printer SSR ( PL 9.3 ).
• Replace the Printer LVPS ( PL 9.3 ).
• Replace the IDFE ( PL 19.1 ).
Check that the Memory DIMMs for the IDFE are correctly installed ( REP 19.3 ).
Replace the IDFE ( PL 19.1 ).
19-003 Hard Disk Fault RAP
NOTE: There are two configurations of the IDFE for this machine. They are identifiable by the
Product Code on the ID tag and by the number of Diagnostic LEDs. Early versions have 5
LEDs and are labeled Product Code GL2. Later versions have 6 LEDs and are labeled Product
Code MFY. This RAP applies generically to both. Where differences between the units exist,
the applicable information is followed by the product code for the specific IDFE.
NOTE: The IOT does not log or display Integrated Digital Front End (IDFE) fault codes.
A 19-003 fault indicates that the applications software could not be successfully loaded and
executed. The amber Heartbeat LED on the IDFE, when continuously energized or de-ener-
gized, indicates a 19-003 fault.
Initial Actions
• Refer to BSD 16.1.
NOTE: Before replacing any of the parts shown in BSD 16.1, ensure that the connectors
for the parts are correctly seated.
• Inspect and re-seat the IDFE DC wiring harness connector P/J899 ( Flag 1 ).
• Refer to OF19-1 IDFE Fault Entry Rap, Figure 1 (GL2) or Figure 2 (MFY), Diagnostic
LEDs and their locations.
Procedure
PO/PO the machine ( GP 8 IDFE Power OFF/Power ON (PO/PO) ).
NOTE: Check the amber Heartbeat LED 70-180 seconds (GL2) or 90 - 120 seconds (MFY)
after PO/PO.
The amber Heartbeat LED is energized or de-energized continuously without blinking.

If an intermittent fault is suspected, perform the following:
•
Reload software using the IDFE CD-ROM Drive ( GP 9 IDFE Software Installation
(CD-ROM) ).
• Go to Flag 1 and Flag 2 of BSD 16.1, and check for loose connections.
• Replace the Printer SSR ( PL 9.3 ).
• Replace the Printer LVPS ( PL 9.3 ).
• Replace the IDFE ( PL 19.1 ).
Perform the following:
•
Reload software using the IDFE CD-ROM Drive ( GP 9 IDFE Software Installation (CD-
ROM) ).
• If the Heartbeat LED does not return to its heartbeat blinking pattern, replace the IDFE
(
PL 19.1 ).
