LED and Channel Verification
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.
