Figure 6-1 Model 743 LED Location
The indications for both HP-UX and HP-RT are as follows:
• When the system is booting or in configure mode, the green LED
(right) on the front panel blinks slowly.
• When the system is running, the green LED is continuously on. A
blinking green light indicates a failure.
The blink patterns occur in blink/second groups. Each blink pattern is
repeated at one second intervals.
Table 6-1 provides more information on the red and green LEDs.
