This read-write integer allows the connected UPS to be disabled, where a set turns off the UPS on systems that support it, and a get or get-next always returns 0. An administrator uses this to remotely power down a UPS unit, for instance during planned decommissioning or safety procedures. For example, before physically disconnecting a UPS for replacement, the admin writes to this object to gracefully turn it off first, where the hardware supports remote shutdown.
