Trivial File Transfer Protocol (TFTP) services allow the switch firmware to be upgraded by transferring a new firmware file 
from a TFTP server to the switch. A configuration file can also be loaded into the switch from a TFTP server, switch settings 
can be saved to the TFTP server, and a history log can be uploaded from the switch to the TFTP server. 

To update the switch’s firmware, click on the Maintenance folder and then the TFTP Services folder and finally click on the 
Download Firmware from TFTP Server link: 

 

Enter the IP address of the TFTP server in the Server IP Address field. 

The TFTP server must be on the same IP subnet as the switch. 

Enter the path and the filename to the firmware file on the TFTP server.  

The TFTP server must be running TFTP server software to perform the file transfer. TFTP server software is a part of many 
network management software packages – such as NetSight, or can be obtained as a separate program. 

Use the Save Changes from the Maintenance menu to enter the address into NV-RAM. 

Click Start to initiate the file transfer.
