To provide a server blade, a blade server device, a server blade control method, a program, and a recording medium for recording a control signal.

The server blade provided with a server function on a single board includes: a detection means for detecting that the server blade is removed; and a storage means for storing a control signal output by a device provided on the server blade, in response to the detection by the detection means as a trigger. Even when a user forgets to record a control signal indicating the state in the server blade before the server blade is removed, the state of the device before the server blade is removed can be known by reading a value automatically recorded.
