For example, an administrator in Taiwan can manage a server in the United States through a remote management device. Under certain circumstances, when the server in the United States fails, the administrator in Taiwan does not need to go to the United States to repair the server in person. Please refer to FIG. 13 , which is a network architecture diagram of traditional remote management. The remote management device is, for example, a network KVM switch 1330 (also known as KVM Over-IP or KVM Over Net), a network power management device 1340 and a network serial device management device 1350 . The network KVM switch 1330 has a network interface 1332 and a computer interface 1334. The network interface 1332 is used to connect to the network 1320, and the computer interface 1334 is used to connect keyboard ports, mouse ports and image output ports of multiple computers. The client computer 1310 at one end of the network 1320 can control multiple computers at the other end of the network 1320 and receive image signals from the multiple computers via the network KVM switch 1330 .

The network power management device 1340 has a network interface 1342 and a power interface 1344 , the network interface 1342 is used to connect to the network 1320 , and the power interface 1344 is used to connect to power ports of multiple computers.

Please refer to FIG. 4 to FIG. 7 at the same time. FIG. 5 is a flow chart of the remote management method, FIG. 6 is a schematic diagram of the first menu, and FIG. 7 is a schematic diagram of the second menu. The remote management method can be used in the remote management system 10 shown in FIG. 1, and includes the following steps:

First, as shown in step 510 , the management server 130 transmits the information of the first remote management device 110 and the second remote management device 120 to the client computer 20 to generate the first menu 60 . The information of the first remote management device 110 and the second remote management device 120 includes, for example, the models of the first remote management device 110 and the second remote management device 120, the number of connection ports, whether the connection ports are on-line, the connection port Type, communication protocol address (IP Address) and media access control (Media Access Control, MAC) address. The first menu 60 lists the connection ports 112(1) to 112(M) shown in FIG. 2 and the connection ports 122(1) to 122(N) shown in FIG. 3 for user management. Therefore, the user only needs to know the IP address of the management server (the user does not need to know the IP addresses of the first remote management device 110 and the second remote management device 120), so that the IP address can be used after logging in to the management server (Login) The first remote management device 110 and the second remote management device 120 perform management.

Since the connection ports 112(1) to 112(M) shown in FIG. 2 and the connection ports 122(1) to 122(N) shown in FIG. 3 are respectively connected to the servers PC-1-1 to PC-1-M and Servers PC-2-1 to PC-2-N, therefore the connection ports 112(1) to 112(M) and connection ports 122(1) to 122(N) listed in the first menu 60 can be server PC-1- 1 to PC-1-M and servers PC-2-1 to PC-2-N (as shown in FIG. 6 ). Next, as shown in step 520 , the management program 140 provides the first menu 60 . In a preferred embodiment, the first menu 60 displays the first remote management device 110 and the second remote management device 120 in a three-level tree structure, and the servers PC-1-1 to PC- 1-M and servers PC-2-1 to PC-2-N, wherein the management server 130 is the zeroth level; the first or second remote management device in the first figure is the first level; the first or second remote management The connection port of the device is second order. In a preferred embodiment, after the first menu 60 is established, if a third remote management device (not shown) is connected to the network 30, the third remote management device will actively communicate with the management server 130 so as to manage the server The 130 can incorporate the third remote management device into management and update the first menu 60 .

Menu 70, and P is less than M+N. In addition, if the first menu has a tree structure of order Q, the order of the second menu is not greater than Q, such as a tree structure of order Q-1. For example, in more detail, the first menu is a three-level tree structure (the management server in the first figure is the zeroth level; the first or second remote management device in the first figure is the first level; the first or second remote The connection port of the management device is the second level), then the second menu is a two-level tree structure (the management server in the first picture is the zeroth level; the connection port of the first or second remote management device is the first level). In other words, the second menu does not display which remote management devices provide these connection ports. On the other hand, since the first remote management device or the second remote management device can be different types of remote management devices, for example, the first remote management device is a network type KVM switch, and the second remote management device is a network type Power management device, therefore the user can freely combine some connection ports of the first remote management device with some connection ports of the second remote management device through the present invention, and the user feels as if he is managing a computer with A "virtual device" that connects ports to power ports. Since the connection ports 112 (1) to 112 (M) and the connection ports 122 (1) to 122 (N) of the aforementioned first menu 60 are connected by the server PC-1-1 to the PC-1-M and the server PC-2- 1 to PC-2-N represent that, therefore, the user selects desired managed server. For example, if the user wants to manage server PC-1-1, server PC-1-2, server PC-2-1, and server PC-2-2, the user selects server PC-2 from the first list 60. 1-1, the server PC-1-2, the server PC-2-1 and the server PC-2-2 to create the second list 70, at this time P is equal to 4. The server PC-1-1, server PC-1-2, server PC-2-1 and server PC-2-2 of the second list 70 respectively represent connection port 112 (1), connection port 122 (2), connection Port 122(1) and connection port 122(2).

Since the number of connection ports listed in the second menu 70 is less than the number of connection ports listed in the first menu 60 (possibly as high as 65535), users can more effectively manage their special interests through the second menu 70. Or the connection port that is particularly important. In other words, the user can create the required connection port menu through a single management interface, so as to improve the efficiency and convenience of operation.

Moreover, in addition to the aforementioned steps 510 to 530, the remote management method can further switch and set the user's authority, so as to provide a flexible user access authorization mode. Wherein, the administrator can set the access authority of each connection port for a specific user.
