What is the purpose of the Reset button?

The Reset button is used to restore the router to the default factory settings if pressed within 5 seconds of router power up. Here is how it works: - The router will not react to the Reset button if it is pressed 5 seconds or more after power up. - When the Reset button is pressed within 5 seconds of bootup and there is no valid xxx.cfg file in the flash memory, the router boots up with the factory defaults stored in nonvolatile RAM (NVRAM). - When the Reset button is pressed within 5 seconds of boot up and there is a valid xxx.cfg file in the flash memory, the router boots up with the xxx.cfg file and avoids the startup-config file in NVRAM. The xxx.cfg default configuration file in flash memory also replaces the startup-config file in NVRAM.
