Using BootP

Upgrading the Gateway
When upgrading the gateway (loading new software onto the gateway) using the
BootP/TFTP configuration utility:
From version 4.4 to version 4.4 or to any higher version, the device retains its
configuration (ini file). However, the auxiliary files (CPT, logo, and the like) may be
erased.
From version 4.6 to version 4.6 or to any higher version, the device retains its
configuration (ini file) and auxiliary files (CPT, logo, and the like).
You can also use the Software Upgrade wizard, available through the Web Interface (see
Software Upgrade Wizard).
To save the cmp file to non-volatile memory, use the -fb command line switches.
If the file is not saved, the gateway reverts to the old version of software after the
next reset. For information on using command line switches, see
Line Switches.
