FTP.
Note that the switch cannot be powered off during loading process.
7.3.2 Loading by TFTP
Remote loading by TFTP is similar to loading by FTP, except that the protocol used for
downloading is TFTP. In this case, the switch can only be used as a TFTP client to
download the software to its Flash from the TFTP server. After the downloading is
completed, the remaining procedure is the same as that in the case of remote loading
by FTP.
7.4 Booting the Switch with Dual Images
The S7502 supports dual image booting: usually the switch boots with the main image
(i.e. the primary file), but uses the backup image (i.e. the backup file) instead when the
main image has any error.
