Power LED Codes

The virtualization engine LEDs are shown in FIGURE 7-1.

FIGURE 7-1Virtualization Engine Front Panel LEDs

Interpreting LED Service and Diagnostic Codes

The Status LED communicates the status of the virtualization engine in decimal numbers. Each decimal number is represented by number of blinks, followed by a

medium duration (two seconds) of LED off. lists the status LED code descriptions.

TABLE 7-2LED Service and Diagnostic Codes

0Fast blink

1LED blinks once

2LED blinks twice with one short duration (one second) between blinks

3LED blinks three times with one short duration (one second) between blinks

...

10 LED blinks ten times with one short duration (one second) between blinks

The blink code repeats continuously, with a four-second off interval between code sequences.
