II. Upgrading Boot ROM Through FTP

1) Connect the FTP server to the router on which Boot ROM is
to be upgraded so that they can communicate with each
other. An FTP server is a device running the FTP server
program.

2) Specify the path on the FTP server to the folder that contains
the Boot ROM upgrade file, and set the username and
password. As shown in

Figure 3-9, configure the username
in the Profile text box and set a password. Make sure the
currently configured path contains the Boot ROM upgrade
file. (For different FTP server software packages, the
interfaces differ).
