Software overview

Installation feature
The upgrade/downgrade of the controller can be performed at boot time using one of the following
methods:
•
•
•
•
•
The controller has sufficient non-volatile memory to store two firmware images. Having a second
firmware image provides a backup in case of failure of the primary image. It also allows for testing
of new firmware on a controller with the ability to easily revert to a previous image.
Configuration management
The controller supports the redundant storage of configuration files to protect against corruption
during a write operation and ensure (at any given time) a valid configuration file exists. If writing the
configuration file fails, it is rolled back and a pre-write file is used.
Text based configuration
The configuration is stored a in human readable format (as a set of CLI commands).
Diagnostics
The following diagnostics are available:
1. In-service Diagnostics – In-service diagnostics provide a range of automatic health monitoring
2.
3. Manufacturing Diagnostics – Manufacturing diagnostics are a set of diagnostics used by

features ensuring both the system hardware and software are in working order.
In-service-diagnostics continuously monitor available physical characteristics (as detailed
below) and issue log messages when warning or error thresholds are reached. There are
three types of in-service diagnostics:
•
Hardware – Ethernet ports, chip failures, system temperature via the temperature sensors
provided by the hardware, etc.
•
Software – CPU load, memory usage, etc.
•
Environmental – CPU and air temperature, fans speed, etc.
Out-of-service Diagnostics – Out-of-service diagnostics are a set of intrusive tests run from
the user interface. Out-of-service diagnostics cannot be run while the controller is in operation.
Intrusive tests include:
•
Ethernet loopback tests
•
RAM tests, Real Time Clock tests, etc.
manufacturing to inspect quality of hardware.
