For example, if the basic network environment of the network storage device 300 is an IP address, "192.168.1.253", the manager terminal is an IP address of any one of the "192.168.1.1" to "192.168.1.252" in the previous network address. Set to switch.

Thereafter, the manager terminal attempts a ping test to the network storage device 300 (610). If the ping test succeeds (615), the manager device is connected to the default IP address of the network storage device 300. Attempt to connect (620).

For example, if the IP address of the manager terminal is "192.168.1.200" and the basic IP address of the network storage device 300 is "192.168.1.253", the manager terminal attempts to connect to the "192.168.1.253".

According to an embodiment of the present invention, the network storage device 300 includes a basic ID / PW at the time of release (for example, ID: "genetwork", PW: "genuser"), if the network storage device ( If the connection to the default IP address is successful (625) (625), the administrator terminal logs in with the basic ID / PW (630), the network environment of the network storage device 300 through the network setting information is the basic The network environment is changed to the actual network environment (635).

If the actual network to which the network storage device 300 is connected has a fixed IP address according to an embodiment of the present invention, in the process of changing the network environment of the network storage device 300 from a basic network environment to a real network environment. The method may include inputting a predetermined fixed IP address to be allocated to the network storage device 300.

If it is confirmed that the network environment of the network storage device 300 is changed from a basic network environment to a network environment in which the network storage device 300 is directly connected (640), the manager terminal is assigned to the network storage device 300. Create (or register) an administrator account (645).

If it is confirmed that a predetermined administrator account is created (or registered) in the network storage device 300 (650), the network storage device 300 deactivates the basic ID / PW and then performs a rebooting procedure. 655), the manager terminal blocks the communication channel connected to the network storage device 300, restores the original network environment of the manager device based on the network setting information (660), and then the network storage device 300. ) Will operate normally on the network.

An implementation method for an initialization process of initializing a disk and registering a user account by logging in to the network storage device 300 as an administrator account after the administrator account is created (or registered) of the present invention. Those skilled in the art will be able to infer various implementation methods for initializing the network storage device 300 with reference to FIG. 7, but the present invention includes all the implementation methods inferred. It is not limited to the implementation method shown in FIG.

In the initializing process of the network storage device 300 shown in FIG. 7, the network storage device 300 management program installed in the manager terminal is interlocked with the disk management unit 515 shown in FIG. 385) and the network storage device 300 management program in association with the user manager 520 shown in FIG. 5 to create at least one user account in the network storage device 300 (or Registration).

Referring to FIG. 7, a client terminal of a manager terminal corresponding to the network storage device 300 (for example, a client in which the network storage device 300 management program is installed among the client terminals 200 connected directly to the network storage device 300) is installed. The terminal 200 accesses the network storage device 300 and logs in with the administrator account created (or registered) in the network storage device 300 through the process shown in FIG. 6 (700). When the network storage device 300 logs in the administrator account, the network storage device 300 checks the validity of the data storage disk 385 provided in the network storage device 300 (705).

According to the exemplary embodiment of the present invention, the validity checking process of the data storage disk 385 includes a process of checking whether the data storage disk 385 includes a logically valid storage space.

If the validity error is confirmed with the data storage disk 385 (710), the network storage device 300 outputs a disk management screen corresponding to the disk management unit 515 to the manager terminal (715). In operation 720, the partitioning and / or formatting process of the data storage disk 385 is performed in association with the manager terminal.

If the partitioning and / or formatting procedure for the data storage disk 385 is completed (725), or if the data storage disk 385 is validated (710), the network storage device 300 The user account for the network storage device 300 is checked for validity (730).

According to an exemplary embodiment of the present invention, the validity checking process for the user account may include checking whether at least one valid user account is registered in the network storage device 300.

If the validation error for the user account is confirmed (735), the network storage device 300 outputs a user management screen corresponding to the user manager 520 to the manager terminal (740), and the manager terminal In operation 745, at least one user account is registered in association.

If at least one user account registration is confirmed (750), or if the validity of the user account is confirmed (735), the network storage device 300 outputs an administrator terminal initial screen corresponding to the administrator account login. (755).
