Resolving Problems when Starting Up

Some of the most common problems that users encounter with PCs occur when they start up their systems. This section describes some problems that may occur in the PA PowerStation during startup and solutions for these problems.

The LED Power indicator on the back of the unit does not light

1Check to see whether the power switch is in the On position, and the PA PowerStation is operating correctly.

a.If the PA PowerStation appears to be operating properly, the LED indicator may be defective. Contact your Parker equipment supplier or Parker Product Technical Support department for assistance.

b.If the PA PowerStation does not appear to be operating properly, restart the PowerStation.

2Check the DC power line to determine whether the DC voltage is either 12VDC or 24VDC.

3Check the power connector to determine whether the leads are properly connected and not reversed. The positive line should connect to the positive terminal, the negative lead should connect to the negative terminal, and the ground lead should connect to the ground terminal.

4Check to see if you have a blown fuse. To replace the fuse, see Replacing the Fuse on page 4-8.

The startup halts with the Award (System Info) screen displayed

1Check for a loose CF card. Restart the PA PowerStation.

The AUTOEXEC.BAT file and/or CONFIG.SYS file does not execute properly

Some startup problems are caused by a corrupted or modified AUTOEXEC.BAT or CONFIG.SYS file. Parker includes backup copies of these files in the \CTC directory on your PowerStation’s CompactFlash Disk and on the PowerStation Start Disk. These files are called AUTOEXEC.CTC and

CONFIG.CTC.

For a complete listing of the AUTOEXEC.BAT and the CONFIG.SYS files, see Appendix B.

If you suspect a problem with either the PA PowerStation’s AUTOEXEC.BAT or CONFIG.SYS files, use the ROM-DOS Copy command to create a backup copy of your current file and overwrite the suspect file with the appropriate backup file. For example, if the AUTOEXEC.BAT file becomes suspect, type the following commands at the ROM-DOS prompt:

copy autoexec.bat autoexec.old copy \ctc\autoexec.ctc autoexec.bat
