Console fails to connect

 

Under certain circumstances, a directly attached console will fail to connect.

This might be the result of the system's communications adapter being deactivated for some reason, such as an exception that took place. This most likely will appear during an IPL and might have an associated system reference code (SRC) on the control panel along with the attention light. You can reset the communications line by performing a function 65 followed by a function 66 on the control panel or remote control panel. To reset the asynchronous communications adapter, you should first deactivate the asynchronous communications line and then activate it again.

To deactivate the asynchronous communications line on the system, follow these steps:

1. If your system is not in manual mode, if the extended functions are not activated, or both, follow these steps:

   1. If your system uses a keystick, insert it in the key slot.

   2. Place the system into manual mode by using the system's control panel.

   3. Using Up and Down, select function 25.

   4. Press Enter.

   5. Use Up to select function 26.

   6. Press Enter.

2. Use Down to select function 65.

3. Press Enter. If the deactivation is successful, the Function/Data window displays D1008065.

To activate the communications line on the system, follow these steps:

1. Use Down to select function 66.

2. Press Enter.

The system attempts to initialize the line. If it is successful, the Function/Data window displays D1008066. If it could not initialize the line, it displays D1008065.
