Figure 108. TFTP File Download
2.  From the File Type list, specify what type of file you want to download to the switch. The 
factory default is Software.
• Sof
tware. The system software image (STK) that 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 corrupted, the system automatically boots from the 
non-active image. This is a safety feature for faults occurring during the 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 
export 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 
Encryption Parameter File (PEM Encoded).
• SSL DH S
trong Encryption Parameter PEM File. SSL Diffie-Hellman Strong 
Encryption Parameter File (PEM Encoded).
Note: It is recommended that you do not overwrite the active image. The 
system will display a warning that you are trying to overwrite the active 
image.
