GS748T Smart Switch
Before you download a file to the switch, the following conditions must be true:
• The f
ile to download from the TFTP server is on the server in the appropriate directory.
• The f
ile is in the correct format.
• The switch has a p
ath to the TFTP server.
To download a file to the switch from a TFTP server:
1. From the File T
ype menu, Specify what type of file you want to download to the switch:
• Code: Th
e 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.
• T
ext 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.
• SSL T
rusted Root Certificate PEM File: SSL Trusted Root Certificate File (PEM
Encoded).
• SSL Server Certificate PEM File: SSL Se
rver Certificate File (PEM Encoded).
• SSL DH W
eak Encryption Parameter PEM File: SSL Diffie-Hellman Weak
