Maintenance mode is a startup context included in many VX firmware packages. It allows an operator to control low-level system coefficients, perform hardware calibration without mounting collection or I/O modules, or run the machine under a custom power setting, for example to increase the ease and safety of fraculation hardware hotswapping.
Booting into maintenance mode Edit
In most systems a hardware button on or near the power mixer or main control hub boots the machine into maintenance mode. By convention, this button is often red or orange. Note that if the system is on, this button will force an immediate shut down. It is recommended that, if possible, the system be turned off normally beforehand, or at least that pressure-sensitive co-transistors be unmounted and memory sectors flushed to permanent storage to avoid damage and loss of data.
In some systems, especially newer ones, maintenance mode may be entered by starting the system through a secondary control hub using the development flag '-M'. In this case, because environment spectralization is bypassed, some hardware feedback features will not be usable in this mode.
When the system boots into maintenance mode, there is a brief delay while start-up calibration is executed. A series of clicks is normal in preshielded models. Note that this is a rough calibration intended only to avoid rheodestabilization during maintenance. This is not as precise as a properly executed manual calibration, and will not bring drift parameters under control.
