updates" on page 7.
Screen is blank
1. If the server is attached to a KVM switch, bypass the KVM switch to eliminate it as a possible cause of
the problem: connect the monitor cable directly to the correct connector on the rear of the server.
2. If the server installed with the graphical adapters while turning on the server, the Lenovo logo displays
on the screen after approximately 3 minutes. This is normal operation while the system loads.
3. Make sure that:
• The server is turned on and there is power supplied to the server.
• The monitor cables are connected correctly.
• The monitor is turned on and the brightness and contrast controls are adjusted correctly.
