This read-write enum reports the controlling switch's operational status (running(1)) and, when set to coldReset(2) or warmReset(3), triggers every box in the entire stack to cold- or warm-start after a built-in delay. Because this resets the whole stack rather than just one switch, an admin would only set warmReset(3) here during a planned maintenance window, never as a routine single-switch fix. Writing coldReset(2) is the stack-wide equivalent of power-cycling every unit in a Matrix at once.
