Solving Problems Described by LCD Status Messages

When a single message appears on the status LCD, locate the code in Table 3-9 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 E0280 MISSING VRM 2 appears, you know that a microprocessor is installed in socket 2, but the VRM for that microprocessor is either improperly installed or missing.

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:

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

•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.

•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:

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

•The system is reset and new error events are detected.

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

System Messages

System messages appear on the console during POST to notify you of a possible problem with the system. If you are performing console redirection, system messages will appear on the remote console. Table 3-10 lists the system messages that can occur and the probable cause for each message.

NOTE: If you receive a system message that is not listed in Table 3-10, check the documentation for the application program that is running when the message appears or the operating system's documentation for an explanation of the message and recommended action.
