3.9 Status Indicators
There is a panel with five LEDs on the gateway upper
cover. The Power indicator signals that the gateway as
a whole is in operation. The other LEDs, marked CH 1
to CH 4, indicate the status of each module.
3.9.1 Power Indicator
Basic diagnostic tests are performed automatically
whenever the gateway is connected to supply voltage.
Each test step is signalled by a specific colour
combination of the LEDs. The testing process is usually
shorter than 0.5 sec and so it looks like a quick
sequence of LED flashes at first sight. If, however, a
test step fails, the indicator combination related to the
failed test remains lighted. This provides a convenient
troubleshooting tool to the technical support personnel.
After all hardware tests have been completed
successfully, the operating system kernel is loaded.
During the process, all module indicators are off and the
blue continuous Power light blinks with the period of
approximately 1 second.
When the operating system kernel has been loaded, the
blue Power indicator keeps shining continuously.
In exceptional cases, when a fatal failure of software
occurs and the gateway stops working, the Power
indicator starts flashing quickly. All you can do is
disconnect the gateway from the power supply for a few
seconds and restart it.
