Software Update
New routing software can be downloaded from a TFTP server.
If you do not have a TFTP server on your LAN, you can use the
included Router Configuration Utility to upgrade the software. This
Windows-based utility has a built-in TFTP emulator enabling you to
use the computer (connected to the LAN and running the Configuration
Utility) to upload the new software to the router.
This is the same Software Update configuration as in the PROM
System Configuration, section Software Update. The parameters are
described in that section.
Perform a System Restart after configuring these settings begins the
software update procedure.
System Restart
The system restart function enables you to reset the DI-1162 without
powering off. Some settings changes require a system restart in order
for them to take effect.
