HIMax System 7 Diagnosis
7 Diagnosis
The diagnostic LEDs are used to give a first quick overview of the system state. The diagnostic
history in SILworX provides detailed information.
7.1 Light Emitting Diodes
Light emitting diodes (LEDs) on the front plate indicate the module state. All LEDs should
be considered together. The state of one single LED is not sufficient to assess the module
state.
The LEDs on the modules are divided into the following groups:
� Module status indicators
� Redundancy indicators
� Rack connection indicators
� System bus indicators
� Slot indicators
� Maintenance indicators
� Fault indicators
� I/O indicators
� Fieldbus indicators
� Ethernet indicators
� Communication indicators
When the voltage is connected, the module performs a test of the LEDs.
When the supply voltage is switched on, a LED test is performed and all LEDs briefly flash
simultaneously.
Definition of Blinking Frequencies
The following table defines the blinking frequencies of the LEDs:
Name Blinking Frequencies
Blinking1 Long (approx. 600 ms) on, long (approx. 600 ms) off
Blinking2 Short (approx. 200 ms) on, short (approx. 200 ms) off, long (approx. 600 ms)
on, long (approx. 600 ms) off

Redundancy Indicators Processor module, system bus module
System Bus Indicators All, except for system bus module
Rack connection indicators System bus module
Slot Indicators System bus module
Fault Indicators Processor module
Maintenance Indicators Processor module
I/O Indicators I/O modules
Fieldbus Indicators Communication module
Ethernet Indicators Processor module, communication module
Communication Indicators System bus module
