[ detailed description ] of the invention
FIG. 1 is a block diagram of a server according to an embodiment of the present invention. Referring to fig. 1, a server 1 is connected to a remote device 2, and the server 1 includes a power supply unit 10, a power management unit 11, a platform path controller (Platform Controller Hub; PCH) 12 and a baseboard management controller 13. The power supply unit 10 is coupled to the power management unit 11 and the baseboard management controller 13, the power management unit 11 is coupled between the power supply unit 10 and the platform path controller 12, and the baseboard management controller 13 is coupled to the power management unit 11. The power supply unit 10 includes a standby power output 101 and a working power output 102, and the power management unit 11 and the baseboard management controller 13 are coupled to the standby power output 101 and the working power output 102 of the power supply unit 10.
Fig. 2 is a flowchart of an embodiment of a remote control method according to the present invention. Referring to fig. 1 and 2, firstly, the server 1 enters a standby mode from an operation mode, the power supply unit 10 outputs an operation power P2 to the power management unit 11 through the operation power output terminal 102 thereof in the operation mode, the power management unit 11 supplies power to the platform path controller 12 according to the operation power P2 to operate in the operation mode, and after the server 1 enters the standby mode, the power supply unit 10 outputs a standby power P1 through the standby power output terminal 101 thereof (step S01). The power management unit 11 and the substrate management controller 13 receive the standby power P1 from the standby power output 101. The baseboard management controller 13 operates according to the standby power P1. The power management unit 11 generates a power signal S1 for the platform path controller 12 to operate on standby according to the standby power P1 (step S02). The power management unit 11 can stop generating the power signal S1 according to the control of the substrate management controller 13. In detail, when the remote device 2 sends the cold reset signal S2, the baseboard management controller 13 controls the power management unit 11 to stop generating the power signal S1 according to the cold reset signal S2 (step S03), so that the platform path controller 12 does not receive the power signal S1, and the platform path controller 12 in standby operation stops the standby operation (i.e. is turned off). Next, the baseboard management controller 13 may calculate a time period (hereinafter referred to as a shutdown period) for which the platform path controller 12 is shutdown, and control the power management unit 11 to regenerate the power signal S1 when the shutdown period of the platform path controller 12 reaches a preset time period (step S04), so as to restart the platform path controller 12 to trigger a cold reset procedure of the server 1.
Therefore, when the user of the server 1 wants to perform a cold reset on the server 1, the user of the server 1 can remotely operate the remote device 2 to control the baseboard management controller 13 to trigger the cold reset procedure of the server 1, and the user of the server 1 does not need to go to the place where the server 1 is installed, and triggers the cold reset procedure of the server 1 by pressing a power button (power button) of the server 1 or by plugging the circuit of the server 1 connected to the ac power supply again, so that the operation is quite convenient. Furthermore, in the present embodiment, the predetermined time period may be 1 second, and the predetermined time period is included in a firmware program executed by the baseboard management controller 13, so that the user of the server 1 can modify the predetermined time period by modifying the firmware program when the user wants to adjust the predetermined time period, which has a considerable modification flexibility in the design of the server 1.
In the present embodiment, after the platform path controller 12 stops the standby operation without receiving the power signal S1, the server 1 enters a mechanical off (G3) mode conforming to the advanced configuration and power interface (Advanced Configuration and Power Interface; ACPI) specification. After the baseboard management controller 13 controls the power management unit 11 to regenerate the power signal S1 (step S04), the platform path controller 12 restarts to cause the server 1 to depart from the mechanical shutdown mode and trigger the cold reset procedure of the server 1.
In practice, the baseboard management controller 13 has a network module, and the baseboard management controller 13 can directly receive the cold reset signal S2 from the remote device 2 through the network module, or indirectly receive the cold reset signal S2 from the remote device 2 through other network units included in the server 1 to control the power management unit 11 to stop supplying power to the platform path controller 12. Furthermore, the power management unit 11 has an enable terminal 111, and the enable terminal 111 is connected to a general purpose input/output (GPIO) pin 131 of the baseboard management controller 13, so that the baseboard management controller 13 can respectively send control signals S3 with corresponding logic levels to the enable terminal 111 of the power management unit 11 under different conditions by the GPIO pin 131, so as to control the power management unit 11 to generate or not generate the power signal S1. In one embodiment, before receiving the cold reset signal S2, the baseboard management controller 13 may send a control signal S3 with a first logic level, for example, a high logic level, to the enable terminal 111 of the power management unit 11 in step S02 to control the power management unit 11 to generate the power signal S1, and after receiving the cold reset signal S2, send a control signal S3 with a second logic level, for example, a low logic level, to the enable terminal 111 of the power management unit 11 in step S03 to control the power management unit 11 to stop generating the power signal S1; and, the baseboard management controller 13 may send a control signal S3 from the low logic level to the high logic level to the enable terminal 111 of the power management unit 11 in step S04 when the period of time that the platform path controller 12 is turned off reaches the preset period of time, so as to control the power management unit 11 to regenerate the power signal S1.
In this embodiment, in step S04, the baseboard management controller 13 further determines whether the power management unit 11 has stopped outputting the power signal S1 after controlling the power management unit 11 to stop generating the power signal S1, if the baseboard management controller 13 determines that the power management unit 11 has stopped outputting the power signal S1, which indicates that the server 1 has entered the mechanical shutdown mode, the baseboard management controller 13 starts to control the power management unit 11 to regenerate the power signal S1 when the calculated time period for which the platform path controller 12 is turned off reaches the preset time period, so that the server 1 is restarted after leaving the mechanical shutdown mode. In practice, the baseboard management controller 13 may detect whether the electric potential on the line of the power supply signal S1 outputted by the power supply management unit 11 is less than a preset electric potential by using an Analog-to-Digital converter (ADC), and take the electric potential of the power supply signal S1 as 5V as an example, the preset electric potential may be 5V, if the baseboard management controller 13 determines that the electric potential on the line of the power supply signal S1 outputted by the power supply management unit 11 is less than 5V, it indicates that the server 1 has entered the mechanical shutdown mode, and the baseboard management controller 13 controls the power supply management unit 11 to regenerate the power supply signal S1 with 5V when the calculated time length of the shutdown of the platform path controller 12 reaches the preset time length.
Fig. 3 is a flowchart of a remote control method according to still another embodiment of the present invention, please refer to fig. 1 and 3 in combination. In this embodiment, before the baseboard management controller 13 receives the cold reset signal S2, the baseboard management controller 13 may control the platform path controller 12 to trigger a warm reset procedure of the server 1 according to the warm reset signal S4 from the remote device 2, so as to reset the server 1 in advance by the warm reset procedure. However, if the platform path controller 12 is not controlled and does not respond to the baseboard management controller 13, that is, the baseboard management controller 13 sends the warm reset signal S4 from the remote device 2, the platform path controller 12 does not trigger the warm reset procedure of the server 1 according to the warm reset signal S4, and the baseboard management controller 13 controls the power management unit 11 to stop generating the power signal S1 according to the cold reset signal S2. Accordingly, the baseboard management controller 13 can determine whether the platform path controller 12 is not responsive to the control of the warm reset before receiving the cold reset signal S2 (step S05), if the platform path controller 12 is not responsive, the baseboard management controller 13 controls the power management unit 11 to stop generating the power signal S1 according to the cold reset signal S2 (step S03), in other words, the user of the server 1 can try to reset the server 1 with the warm reset by the remote device 2 before the remote device 2, and if the remote device 2 is not operated again to reset the server 1 with the cold reset.
In the present embodiment, if the server 1 is first operated in the operation mode and receives the cold reset signal S2 from the remote device 2 in the operation mode, the server 1 is switched from the operation mode to the standby mode according to the cold reset signal S2. In this case, the baseboard management controller 13 receives the cold reset signal S2 when the server 1 is in the operation mode, and after the server 1 is switched from the operation mode to the standby mode, the baseboard management controller 13 outputs the control signal S3 with the first logic level to the enable terminal 111 of the power management unit 11 through the GPIO pin 131, so that the power management unit 11 outputs the power signal S1 according to the standby power P1 in the standby mode, and then the baseboard management controller 13 outputs the control signal S3 with the second logic level to the enable terminal 111 of the power management unit 11 through the GPIO pin 131, so that the platform path controller 12 stops operating; in another embodiment, if the server 1 is switched from the working mode to the standby mode by the user directly operating the server 1 at the location before receiving the cold reset signal S2, the server 1 receives the cold reset signal S2 from the remote device 2 while in the standby mode. In this case, the baseboard management controller 13 outputs the control signal S3 with the first logic level to the enable terminal 111 of the power management unit 11 through the GPIO pin 131 in the standby mode before receiving the cold reset signal S2, so that the power management unit 11 outputs the power signal S1 according to the standby power P1 in the standby mode, and after the baseboard management controller 13 receives the cold reset signal S2 in the standby mode, the baseboard management controller 13 outputs the control signal S3 with the second logic level to the enable terminal 111 of the power management unit 11 through the GPIO pin 131 in the standby mode, so that the platform path controller 12 stops operating.
In summary, according to an embodiment of the server and the remote control method thereof, when a user of the server wants to perform a cold reset on the server, the user of the server can remotely operate the remote device to control the baseboard management controller to trigger the cold reset program of the server, and the user of the server does not need to go to the location of the server, and the user of the server can trigger the cold reset program of the server by pressing a power key of the server or by re-plugging the server into a circuit connected to an ac power supply, which is quite convenient in operation.
