The CoreBuilder 5000 hub's controller module is equipped with an LED
Test button on the front panel. The LED Test button is used to verify
LED operation. When you press this button, the module initiates a test
to all modules in the hub. All LEDs should respond by lighting
continuously for approximately five seconds. Any LED that does not
light is defective. This test will not disrupt network operation.
