Techopedia Explains Warm Plugging

As the name implies, warm plugging fits somewhere between hot and cold plugging. In hot plugging a device can be replace without turning the computer off. In cold plugging, the computer must be turned off to replace a device. So, in warm plugging, the while the power and OS remain on, activity must be stopped on the bus that the device is connected to. You can think of this as better than a cold swap but worse than a hot swap.
