•
WNPS daughterboard failure (for TVBAH#A or S#A)
•
Failure of N28 power supply on TVBAS2B or TVBAH#B
•
I/O pack P28 voltage is low
•
The terminal board has failed
Solution

66
Description
Dual Ethernets not supported with 10 ms frame rate
Possible Cause
The second Ethernet port is connected, but not supported for a 10 ms frame rate.
Solution
•
Remove the second Ethernet connection to the YVIB.
•
Increase the frame rate to 20ms.
•

67
Description
Pack internal reference voltage out of limits
Possible Cause
The I/O pack failed to auto-calibrate when powered on.
Solution
Replace the I/O pack.
68
Description
Internal daughterboard temperature limit exceeded ([ ] °F)
Possible Cause
•
The cabinet temperature is too high.
•
The I/O pack overheated.
•
If the cabinet temperature is within the specified temperature limits, the I/O pack internal daughterboard temperature
sensor may have failed.
Solution
•
Check the environmental controls applied to the cabinet containing the I/O pack. Operation will continue correctly
beyond these temperature limits, but long-term operation at elevated temperatures may reduce equipment life.
•
If the I/O pack internal daughterboard temperature sensor failed, then replace the I/O pack.
