The following sections describe functions that allow you to:

❑

check the module's channel assignment and LED functionality

❑

remotely manage the Bridge Module from another device

The ONline Controller Module is equipped with an LED check button on the 
front panel.  The LED check button has two functions: it causes all LEDs in 
all modules in the concentrator to light, and it causes each module to 
identify the channel to which it is assigned.  When you press this button, 
the module initiates a test to all modules in the concentrator.  Any LED that 
does not light is defective.

After the five seconds elapse, the diagnostic continues with a channel 
check of all modules.  Each Port Status LEDs should respond by blinking the 
number of times to correspond with the channel to which it is assigned.  
The channel check sequence repeats five times.  Table 2-3 explains the 
channel check codes.
