Solving Problems Described by LCD Status Messages The code and text on the LCD can often specify a very precise fault condition that is easily corrected. For example, if the code E0708 PROC_1_Presence 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: • Clear the SEL - You can perform this task remotely, but you will lose the event history for the system. • 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. 32 About Your System
