An LED (Light Emitting Diode) is an object used to represent a state through a color. Most types of equipment use LEDs as interfaces that give the user information on hardware and software conditions. ILOG JViews TGO provides an LED business object to help you create real world items of equipment.

Although a state object can be associated with LEDs, it does not affect their graphic representation. LEDs are not managed objects themselves; they help represent the state of managed objects such as ports or cards.

Depending on the nature of the application, LEDs can be represented by a bitmap image or by a vector graphic. Like a network element, the LED representation is set through the TypeAttribute attribute assigned to the object represented by the LED.
