Uploading Files
Use the following procedures to upload a file from a TFTP server to the switch.
1. From the File Type field, select the type of file to copy from the switch to the TFTP server.
2. If you are uploading a D-Link DWS-4000 Series image (Code), select the image on the switch to upload. If
you are uploading another type of file, the Image Name field is not available.
3. Complete the TFTP Server Address Type, TFTP Server IP Address, and TFTP File Name (full path without
TFTP server IP address) fields.
4. Click the Start File Transfer check box, and then click Submit.
After you click Submit, the screen refreshes and a “File transfer operation started” message appears. After
the software is downloaded to the device, a message appears indicating that the file transfer operation
completed successfully.
Multiple Image Service
The system maintains two versions of the D-Link DWS-4000 Series software in permanent storage. One image
is the active image, and the second image is the backup image. The active image is loaded during subsequent
switch restarts. This feature reduces switch down time when upgrading/downgrading the D-Link DWS-4000
Series software.
The system running an older software version will ignore (not load) a configuration file created by the newer
software version. When a configuration file created by the newer software version is discovered by the system
running an older version of the software, the system will display an appropriate warning to the user.
Use the Multiple Image Service page to set the boot image.
To display the Multiple Image Service page, click Tool > Multiple Image Service in the navigation menu.
