Fan and Physical Security Sensors describes the fan and security sensors. In the table, n designates numbers 0, 1, 2, etc.

Table 4-5 Fan and Physical Security Sensors

Sensor Name	Sensor Type	Description
/SYS/FB/FANn/TACH	Fan speed	Fan board; Fan `n` tachometer
/SYS/INTSW	Physical security	This sensor tracks the state of the chassis intrusion switch. If the server's top cover is opened while the AC power cords are still connected so that power is being applied to the server, this sensor asserts. If the top cover is subsequently replaced, this sensor is de-asserted.
