Boot Process
When power is applied to the Secure Router, the Flash is checked for a downloadable boot
image. If a boot image file is found in the Flash, the file is executed. Otherwise, the boot
image is executed from the factory image stored in the boot ROM. Next, the Nortel operating
Secure Router is loaded from the T1000.Z file residing in the Flash. Power-up diagnostics such
as flash test, memory test, etc. are run and then the Ethernet and WAN interfaces are
installed. The router is then configured using settings previously saved in the system.cfg file.
Once these settings are configured, the router is ready for operation and user login.
