What is H3C S7500E Series LAN Switch software upgrade? It refers to download
new applications to the routing switch unit of the switch.
There are three ways of software upgrade for H3C S7500E series LAN Switch:
Use TFTP protocol to upgrade through the Ethernet interface of the routing switch
unit;
Use FTP protocol to upgrade through the Ethernet interface of the routing switch unit;
Use XMODEM protocol to upgrade through the Console port of the routing switch unit.
Using Ethernet interface, the first two ways come in faster download. Setting user
name and password is necessary for FTP, so dos not TFTP.
The last one comes in slower download as it uses a serial interface.
