Solving Problems Described by LCD Status Messages

When a single message appears on the status LCD, locate the code in Table2-8 and perform the suggested corrective action. The code on the LCD can often

specify a very precise fault condition that is easily corrected. For example, if the code E0780MISSING CPU 1 appears, you know that a microprocessor is not

installed in socket 1.

In contrast, you might be able to determine the problem if multiple related errors occur. For example, if you receive a series of messages indicating multiple

voltage faults, you might determine that the problem is a failing power supply.



Removing LCD Status Messages

For faults associated with sensors, such as temperature, voltage, fans, and so on, the LCD message is automatically removed when that sensor returns to a

normal state. For example, if temperature for a component goes out of range, the LCD displays the fault; when the temperature returns to the acceptable

range, the message is removed from the LCD. For other faults, you must take action to remove the message from the display:

l Clear the SEL — You can perform this task remotely, but you will lose the event history for the system.

l Chassis intrusion — When you remove the cover, the system assumes that you are servicing the bad component; the LCD clears when you replace the

cover.

l Power cycle — Turn off the system and disconnect it from the electrical outlet; wait approximately ten seconds, reconnect the power cable, and restart

the system.

Any of these actions will remove fault messages, and return the status indicators and LCD colors to the normal state. Messages will reappear under the

following conditions:

l The sensor returns to a normal state but fails again, resulting in a new SEL entry.

l The system is reset and new error events are detected.

l A failure is recorded from another source that maps to the same display entry.

System Messages

System messages appear on the screen to notify you of a possible problem with the system. Table2-9 lists the system messages that can occur and the

probable cause and corrective action for each message.

NOTE: If you receive a system message that is not listed in Table2-9, check the documentation for the application that is running when the message

appears or the operating system's documentation for an explanation of the message and recommended action.

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See

your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting against

electrostatic discharge.
