AT&T 3.0 manual System Busy, Other Error Conditions, Power Cycle During Installation

Processor Problems

System Busy

If the forced installation is attempted while a line/trunk or extension is busy, the following screen appears.

System Busy - Pls Wait

Dial Code:xxxx S/P:ss/pp

Exit

When all lines/trunks or extensions are freed, the installation continues. Select Exit to return to the System menu and cancel the installation. If system software is corrupted, system maintenance may not provide an accurate indication of busy lines/trunks or extensions. If this seems to be the case verify that the listed extensions are truly not busy; then perform the installation by power-cycling the system. See Step 3 above.

Other Error Conditions

The following error conditions may not be viewed on the error code/status display or the maintenance screens.

Power Cycle During Installation

The system automatically begins the installation procedure again. If the power source is unreliable, it is possible for the installation procedure to retry indefinitely. See “Power Supply Problems” or Chapter 2 ofInstallation for details on providing a reliable power source.

Removal of Memory Card During Installation

The system is in an indeterminate state. Re-initiate the forced installation by power-cycling the system after inserting the memory card.

Incompatible Releases

If releases are incompatible, see System Programming and Maintenance (SPM) for instructions on converting the system programming before upgrading to the new release.
