Status LEDs
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.
There are five possible states for a SmartNode:
•
Normal boot process (Normal Boot). The SmartNode starts the normal application, that is the configura-
tion 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 on 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 40
.
