IMG 1004 - Front Panel Status LEDs

 

On the IMG 1004 there are multiple LED's each displaying a specific status. All LED's are controlled by either software or firmware depending on whether the unit is booting or not. Once software is loaded, and the system is ready to run calls, the LED's are controlled by software. The first section below explains what the LED will display while software is loaded and the system is ready to pass calls.  During the bootup process the IMG 1004 goes through an internal diagnostic that checks different aspects. The second section below explains what is displayed when the LED's are under firmware control.

LED STATUS (bootup)

The IMG 1004 utilizes the LED's on the front panel to display different aspects of the boot sequence. As the IMG 1004 goes through its boot process the LED's will indicate what part of the boot process the IMG 1004 is checking and whether any problems were encountered. Below is a chart showing what the LED's will display as the boot sequence progresses.

 

BOOTUP

The first table below is a table of the Bootup Process. When the IMG 1004 is first powered up or when it is reset it will go through the sequence of LED's shown below under BootUp Process.
