ALARM 3F: CSMA/CD BUS ERROR: PORTx ELAyy INOPERATIVE hhmmssref code
Cause:
Action:
CSMA/CD adapter cable
CSMA/CD
LAN component
CSMA/CD LAN interface
Local CSMA/CD adapter cable
SQE test function disabled on a MAU (transceiver).
• Contact the administration responsible for this LAN.
• Check and correct CSMA/CD installation or cable connections.
• Check that the SQE test switch on MAUs (transceivers) is enabled.
• Reactivate the resource.
• If the problem persists,
CO
the hardware support and give the reference code.
ALARM 40: SOFTWARE ERROR: CCU·x RE-IPL IN PROGRESS hhmmss ref code
Cause:
Action:
Control program abend. The problem may be caused by hardware, software or a mistake in
specifying parameters. The abend code will appear on the ELD screen.
Abend codes are explained in the NCP, SSP, and EP Messages and Codes.
Take action as appropriate for the detailed explanations of the abend code in the NCP, SSP,
and EP Messages and Codes manual.
If the problem persists or occurs repeatedly,
CO
the software support and give reference
code and atrend code.

• Transfer the control program dump to the host and print it. Refer to the NCP, SSP, and
EP Diagnosis Guide.
• Resume operations and perform problem determination procedures. If the problem
occurs repeatedly:
Look for the control program abend code displayed in the previous BER (Event Log
Display function in the 3745 Advanced Operations Guide).
Refer to the appropriate control program documentation (NCP or else) for the abend
code xxxx description.
Check and, if necessary, correct generation parameters. There may be a mismatch
between hardware configuration and software generation parameters.
