11 LED INDICATIONS
The LEDs on the SmartNode provide information about the status of the device and its interfaces.
They are located on both the front and the rear of the device.
Indication is conveyed by [on / off] and [steady / blinking] states, not by color change.
Depending on the type of SmartNode that you have installed, some LEDs may not be available.
The indications provided by LED states are described in the table. The terms in (brackets) in the
following list refer to the headings in the table overleaf.
There are five possible states for a SmartNode:
•
Normal boot process (Normal Boot). The SmartNode starts the normal application, that is the
configuration stored in the flash memory.
•
Normal operating behavior (Normal Run). The SmartNode is running the normal
application that is the configuration stored in the flash memory.
•
Boot loader started (Boot Loader). The boot loader started instead of the normal application.
Refer to the
Software Configuration Guide
for more details of the boot loader.
•
Default download in progress (Default Download). A configuration file is downloaded for
the first time to the flash memory, i.e. the configuration file
default-config
in the storing
location
nvram:
does not exist yet. It means that a configuration file is being downloaded.
•
Error state (Error State)
If neither the normal application nor the boot loader are running, the device may have a more
serious problem. The error state is indicated by the LEDs as described in Table 11-1 below.
