Table 62 IOP Box Soft Failure Error Codes
Error
Code Failure
Mnemonic
Description Corrective Action
40 EEFAILED Output EEPROM write failure. If an HLAI or AO, replace the IOP. If an LLAI,
replace the affected plug-in module.
41
VREFFAIL LLMUX FTA ref voltage failure If the problem persists replace the FTA
42 ADOUTUDF Analog to digital conversion value
underflowed (HLAI only). Check the input wiring at the FTA; possible bad
contact. Otherwise, replace the IOP card and/or
the FTA.
43 ADOUTCAL HLAI A/D is out of calibration by more
than ±3%.(refer to the “IOP
Calibration Procedures” section). Calibrate or replace the IOP card (refer to the
“IOP Calibration Procedures” section).
44 BADFLREG AO IOP failure selection register is
bad. Replace the AO IOP card.
45 BDSNDTC Bad output module secondary latch. Replace the IOP. Use a Standby Manual device
if nonredundant.
46
BDOUTBFR Bad output buffer. Replace IOP. Use Standby Manual device if
nonredundant.
47 VCALFAIL Calibration reference out of range. Replace the IOP or recalibrate.
48
F1NOTCAL LLMux or RHMUX: FTA 1 is not
calibrated.
SI: FTA 1 write buffer has
overflowed. LLMux or RHMUX: Calibrate FTA 1.
SI: Reduce the number of writes to the FTA.
49 F2NOTCAL LLMux or RHMUX: FTA 2 is not
calibrated.
SI: FTA 2 write buffer has
overflowed. LLMux or RHMUX: Calibrate FTA 2.
SI: Reduce the number of writes to the FTA.
50
F1COM_FL LLMux or RHMUX: FTA 1 fails to
communicate.
SI: FTA 1 fails to communicate. Check the connection from the Power Adapter
to FTA 1. If the FTA is missing, install the FTA.
If the FTA is present, replace the FTA.
51
F2COM_FL LLMux or RHMUX: FTA 2 fails to
communicate.
SI: FTA 2 fails to communicate. Check the connection from the Power Adapter
to FTA 2. If the FTA is missing, install the FTA.
If the FTA is present, replace the FTA.
52
F1_IDERR FTA #1 is pinned as #1. Verify/correct the FTA pinning.
53 F2_IDERR FTA #2 is pinned as #0. Verify/correct the FTA pinning.
54 F1VREFFL FTA 1 has a reference voltage
failure. Replace the FTA.
55 F2VREFFL FTA 2 has a reference voltage
failure. Replace the FTA.
56 F1CAL_FL FTA 1 calibration procedure failed. Recalibrate the FTA.
