Troubleshooting and tips
8.4
No screen display or display drifts
1
The wrong horizontal frequency or resolution has been selected for the
monitor or for the application program.
Ê
Find out which horizontal frequency your monitor screen supports. You will
find the horizontal frequency (also known as line frequency or horizontal
deflection frequency) in the documentation for your monitor.
Ê
Refer to the documentation for your operating system or the software for the
screen controller for details of how to set the correct horizontal frequency for
your monitor, and follow the procedure accordingly.
8.5
Incorrect date and time
Ê
Set the date and time in the operating system or in the BIOS Setup under
the Main menu, using System Date and System Time respectively.
I
Note that the operating system may affect the system time. For example,
the operating system time may deviate from the system time under
Linux, and would overwrite the system time in the default setting on
shutdown.
If the date and time are still wrong after the server has been switched off and
back on again, replace the lithium battery (for a description refer to the
PRIMERGY BX920 S4 Server Blade Upgrade and Maintenance Manual) or
contact our customer service team.
8.6
System will not boot
The system will not boot after installing a new hard disk drive.
SAS configuration incorrect
Ê
Check the settings for the hard disk drives (SAS Device Configuration) and
the additional settings in the SAS configuration menu.
