Trivial File Transfer Protocol (TFTP) transmissions are initiated by the client. When 
downloading a file, the client sends a read request packet to the TFTP server, 
receives the data packets from the server, and sends the ACK to the server. When 
uploading a file, the client sends a write request packet to the TFTP server, then 
sends the data packets to the server, and receives the ACK from the server. The 
TFTP transmission files have two forms; binary for program transmission and ASCII 
for text transmission.

To upgrade the software using TFTP perform the following steps. 

n

1 Connect the switch to a PC where the file is located using the 

management/upgrade Ethernet port. (You need the IP address of the PC. At the 
same time, connect the switch to an external PC (that can be the same one that 
contains the file) using the console port.

2 Run the TFTP server program on the PC connected to the management/upgrade 

Ethernet port and specify the path for upgrading the application files.

3 Run the terminal emulation program on the PC connected to the console port, 

and boot the switch to access the Boot menu.
