error is associated with a microprocessor or with a microprocessor socket.

 

 

• If the error is associated with a microprocessor, replace the microprocessor.

 

 

• If the error is associated with a VRM, replace the VRM.

Monitor problems

Some monitors have their own self-tests. If you suspect a problem with your monitor, see the documentation that comes with the monitor for instructions for testing and adjusting the monitor.

•Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved.

•See the parts listing in the Hardware Maintenance Manual to determine which components are customer replaceable units (CRUs) and which components are field replaceable units (FRUs).

•If an action step is preceded by “(Trained service technician only),” that step must be performed only by a trained service technician.

Symptom

Action

 

 

Testing the monitor

1. Make sure that the monitor cables are firmly connected.

 

2.

Try using a different monitor on the server, or try using the monitor that is being

 

 

tested on a different server.

 

3.

Run the diagnostic programs. If the monitor passes the diagnostic programs,

 

 

the problem might be a video device driver.

 

4.

(Trained service technician only) Replace the system board.

 

 

The 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.

Make sure that:

 

 

• The server is turned on. If there is no power to the server, see “Power

 

 

problems” on page 99.

 

 

• The monitor cables are connected correctly.

 

 

• The monitor is turned on and the brightness and contrast controls are

 

 

adjusted correctly.

 

 

• No POST errors are generated when the server is turned on.

 

3.

Make sure that the correct server is controlling the monitor, if applicable.
