See the operating manual of the display unit.

6When running Windows NT/2000, boot up in the VGA mode, and make sure that the settings (resolution, synchronizing fre- quency) are as supported by the display unit.

Characters are distorted or not displayed properly

Probable causes are faulty connection of the display signal cable or power cable, or a problem with the brightness or contrast set- tings. Carry out the following procedure to check the cause of the trouble. If this does not remedy the problem, see “Remedy When Windows NT/2000 is Unusable” on page 213.

1Is the display unit properly connected to the server?

If the switch box is used on a Rack Type, also check the con- nections with other devices and that the server is properly selected.

See “How to connect peripheral devices” on page 26.

2Switch on the display unit, and set the brightness and contrast to two thirds of the maximum value or more.

See the operating manual of the display unit.

3When running Windows NT/2000, boot up in the VGA mode, and make sure that the settings (resolution, synchronizing fre- quency) are as supported by the display unit.

The system status indicators and disk status indicators turn on abnormally

When the lit state of the system status indicators and disk status indicators differs from the specifications described in this manual, a probable cause is malfunction of the indicator, faulty cable con- nection, or other internal trouble on the server. If Windows NT/ 2000 can be used, see “Remedy When Windows NT/2000 is Usable” on page 212.

If Windows NT/2000 cannot be used, see “Remedy When Windows NT/2000 is Unusable” on page 213.
