LED and Network Verification

Once the module is installed, verify its operation through the front panel of the ONline Controller Module. The Controller Module is equipped with an LED test button on the front panel. Use the LED test button to verify LED operation and verify network assignment.

When you press this button, the Controller Module initiates a test to all modules in the concentrator. All LEDs should respond by lighting continuously for approximately five seconds. Any LED that does not light is defective.

After the five seconds elapse, the diagnostic continues with a network check of all modules. Each Status LED should respond by blinking the number of times to correspond with the network to which the module is assigned. The network check sequence repeats five times. If a module is in isolated mode, the Status LEDs on the module remain off. The Activity LED remains on during the network check sequence. This test does not disrupt network operation. Table 3-5 explains the network check codes

Table 3-5. Network Check Codes

	LED State	Network Configuration

1	Blink	Module is configured for network 1

2	Blinks	Module is configured for network 2

3	Blinks	Module is configured for network 3

Off		Isolated (module operates independent of
		any network)
