GS748T Smart Switch
To upload a file from the switch to another system by using HTTP:
1. From the File Type menu, specify what type of file you want to upload from the switch:
• Code: The code is the system software image, which is saved in one of two flash
sectors called images (image1 and image2). The active image stores the active copy;
while the other image stores a second copy. The device boots and runs from the
active image. If the active image is corrupt, the system automatically boots from the
non-active image. This is a safety feature for faults occurring during the boot upgrade
process.
• Text Configuration: A text-based configuration file enables you to edit a configured
text file (startup-config) offline as needed without having to translate the contents for
the switch to understand. The most common usage of text-based configuration is to
upload a working configuration from a device, edit it offline to personalize it for
another similar device (for example, change the device name, serial number, IP
address), and download it to that device.
2. If you are uploading an GS748T image (Code), select the image on the switch to upload to
the management system. This field is visible only when Code is selected as the File Type.
3. Click Apply. A window appears to allow you to open the text file on the management system
or to save the image or text file to the management system.
4. Click Cancel to cancel the operation on the screen and reset the data on the screen to the
latest value of the switch.
Download File To Switch

You can also download files via HTTP. See HTTP File Download on page 256 for additional
information.
To access the TFTP File Download page, click Maintenance  Download  TFTP File
