1 Immediately switch the server off, and disconnect the plug
from the AC outlet.
2 Does the installation site satisfy the environmental consider-
ations (e.g. ambient temperature and humidity)?
See “Environmental considerations” on page 5.
3 Are there any foreign objects blocking ventilation holes?
Nothing happens if you press the power switch. Or, nothing
appears on screen even though you can hear the server run-
ning
Probable causes are that the peripheral devices or cables are not
correctly connected, or fatal trouble has occurred on the server.
Carry out the following procedure to check the cause of the trou-
ble. If this does not remedy the problem, see “Remedy When
Windows NT/2000 is Unusable” on page 213.
1 Are the keyboard, mouse, and 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.
2 Is the PCI expansion card properly inserted into the appropri-
ate slot on the motherboard, and is it held firmly in place by the
PCI bracket?
See “Installing/removing an optional device” on page 52.
See “Expansion cards” on page 103.
3 Are the power cables for the server and display unit properly
connected to a grounded AC outlet?
See “Connecting the power cable” on page 31.
4 Is the power indicator ( ) lit amber?
5 Switch on the display unit, and set the brightness and contrast
to two thirds of the maximum value or more.
