32 About Your System
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.
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 screen to notify you of a possible problem
with the system. Table 1-3 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 1-3, check the
documentation for the program that is running when the message appears or the
operating system's documentation for an explanation of the message and
recommended action.
