Meanwhile, the environmental monitoring result in the cabinet can be simply displayed through acousto-optic alarm, and the alarm signal is controlled. The switch unit can clearly and definitely display the current state of the cabinet, and interaction steps between people and the cabinet are simplified.
Compared with the defects of the existing switch unit, the switch unit comprises two operation modes, namely a local manual mode and a remote automatic mode, and an operator can select an appropriate mode to operate according to the field environment. Under some circumstances, an operator is not convenient to operate buttons on a control panel nearby the data center, and at the moment, the data center and each resource module can be remotely turned on and turned off only by sending corresponding on and off instructions to the single chip microcomputer inside the switch unit through the serial port, so that the operation of the data center is more flexible and convenient. In the remote automatic mode, the switch unit module provides a one-key power-on and power-off function. An operator only needs to send a one-key startup and shutdown instruction to the single chip microcomputer in the switching unit at the client, and the switching unit can complete the startup and shutdown operations of all resource modules according to the time sequence set in the code, so that the remote automatic startup and shutdown of the data center is realized.
