Software Update
New routing software can be downloaded from a TFTP server. All
configuration settings will be retained through the software update
process.
If you do not have a TFTP server on your LAN, you can use
RouteMan, the included Router Configuration Utility. This Web-based
utility has a built-in TFTP emulator , which allows you to use the
computer (connected to the LAN and running RouteMan) to upload the
new software to the router.
This is the same Software Update configuration screen as in the
PROM System Configuration, Software Update section. The
parameters are described in that section.
Perform a System Restart after configuring these settings to begin the
software update procedure.
