Problem-Solving Using the LEDs A-3
Normal Powerup
When power to the module is initially applied, the following events
occur:
Event Description
1. Upon receiving power, the module’s Power LED lights
immediately and the Module OK LED lights within five
seconds. Also upon receiving power, the module performs a self-
test. The self-test should complete in 25 seconds for a module
with 4MB of memory and 67 seconds for a module with 16MB of
memory. During the course of the self-test, all of the LEDs will
turn on briefly.
2. After the module completes self-test, the Power LED , the
Module OK LED , and the Network OK LED remain lit.
The Network Activity LED blinks at a rate proportional to
the amount of activity on the port.
3. The remaining LEDs indicate their operational status, as
described in Table A-1.
Note
During Set-Up and Configuration, the Module OK LED will
not be lit until Set-Up is completed or Configuration is exited.
Problem Solving Using the LEDs
When diagnosing a problem with the module, note that the problem is
often indicated by the states of the module LEDs. Table A-2 lists the
states of the LEDs for various error conditions that can occur during
initial installation of the device, along with probable causes and
corrective actions to take.
