CHAPTER 1 Product Outline

LED (CHECK LED/POWER LED)

The POWER LED indicates whether the system is turned on while the CHECK LED indicates system operation by lighting up or blinking.

	Table 1.2 POWER LED
Status	Descriptions
ON	The power is on
OFF	The power is off

The user and system administrator can recognize the system operation status from the CHECK LED and messages that appear on the LCD panel.

	Table 1.3 CHECK LED
Status	Descriptions
ON	The system is turned on, but the processors are not operating.
Blinking	System down.
(quickly)
Blinking	There are faulty components in the system. (The system is still
(slowly)	operating)

OFF

The system is not turned on or it is operating normally

If the system administrator shuts down the system (when the AC main line switch is on) while there are degraded-mode components remaining in the system, the CHECK LED will continue to blink slowly to remind the system administrator there are faulty components to be diagnosed. Possible causes of a CHECK LED alarm are: errors in temperature monitoring, related components (such as the power supplies and fans) or degraded-mode components (such as processors and memory modules, etc.).

When the system is turned on, the CHECK LED lights up briefly. However, this is not an error unless the CHECK LED remains light up for more than three seconds, or begins to blink.

LCD The LCD panel can display 2 rows of 16 digits. The messages displayed on it are status or results of the power-on diagnostics, and environmental events such as over temperature, etc. Therefore, when an error occurs, the user or system administrator can recognize the state of the hardware system easily by checking the messages displayed on the LCD panel as well as console messages.

Error messages remain on the LCD panel until the error is corrected. There is only one LCD panel, therefore, it displays messages in turn when there are several errors. Note that error events are corrected even though their message displayed on the panel is overwritten by messages of other events. However, since the initial diagnostics is allowed to report only one event, the next message of another event will be displayed on the panel after repaired a reported event.

Messages are erased from the panel when: an error event is corrected.

the power of the main cabinet is cycled

￿the AC main line switch is turned off, or

the RESET switch is pressed (partial messages are erased).

When an error or an abnormal state occurs, record the messages displayed on the LCD panel and status of the CHECK LED. Then, contact the system administrator or service engineers. See 14 "Troubleshooting" for more information regarding the messages displayed on the LCD panel.
