2. DESCRIPTION OF OPERATION

2.5 Initialization processing

Description

· The state of initialization is indicated by LED (Power Supply LED, initialization LED 1, 2, 3).

· The Power Supply LED is blinking in ﬁrst step. In the case of the Power Supply is abnormaly, the LED is blinking at high speed.

· The initialization is start with turning on the Main Power Supply by turning on the Power Supply Switch in state of turning on of the Main Power Supply Switch.

When problem occur

It's possible Memory error, in case extinction the LED 1,2,3 or blink the LED2,3 when power switch turn on. Change the Memory DIMM and check retrieve.

In case LED1,2,3 stop at Step1 to 6, trouble occur the board. Change the Main board.
