OF19-1 IDFE Fault Entry 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: Centerware Network Services is the official name for “web client” and “web UI.”
NOTE: The IOT does not log or display Integrated Digital Front End (IDFE) fault codes.
This RAP is intended to help analyze the fault code(s), indicated by the LED display on the
IDFE, or by the Configuration Report and to direct the field service representative to the appli-
cable RAP.
Initial Actions
• Refer to BSD 16.1.
• Verify that the DC wire harness connector, P/J 889 is correctly seated into the IDFE.
• From your machine log, obtain the Configuration Report and verify that the version of firm-
ware and software for the IDFE and the IOT are compatible.
Procedure (Product Code GL2)
NOTE: Before evaluating the fault indicated by the Diagnostic LEDs, allow 70-180 seconds to
pass for the Diagnostic LEDs to come to a steady state condition after the IDFE has been
switched-on.
NOTE: If more than one fault is detected the first error encountered is the one displayed.
NOTE: If a hard fault is detected during power up, the software boot sequence test stops. If a
soft fault is detected, the Software boot process will continue.
Switch on the power. Observe the IDFE Diagnostic LEDs ( Figure 1 ) as the system performs
self -test. Compare the observations with the Fault Indication descriptions in Table 1 and
Table 2 . Refer to Table 3 for a description of the function of each LED.

Within 10 seconds of Power-On if any of the LEDs on the
IDFE are de-energized or if the Green Power LED is de-
energized.
NOTE: After a PO/PO is performed all LEDs should
energize for approximately 10 seconds. If this does not
occur, perform RAP 19-001.
