Introduction
Cisco's 3800 series include 4 different type of routers: Cisco 3825, Cisco 3825-NOVPN, the Cisco 3845, and the Cisco 3845-NOVPN. Depending on the series of the router, there will be different methods of resetting. All Cisco routers will use the ROMMON mode to reset if a password was configured. ROMMON mode is to be used for troubleshooting purposes, or if a password from a previous configuration has been forgotten. The following is the method to reset a Cisco 3800 Series router.
Clearing Configurations on a Cisco 3800
If a router has a previous configuration, a network administrator may have to clear the configurations in order to configure the necessary components needed on a network. As such, ensure that the router is accessible; SSH or Telnet can be used to remote access, but otherwise access through console. Before proceeding to clear the configurations, connect the console rollover cable. The pin-end should be connected to the corresponding port on the host device, and the RJ45 end should be connected to the console port found behind the router. A terminal to get access the router is needed. Some popular terminals include TeraTerm, PuTTY, and SecureCRT (make sure to have an of these installed on the host device) .
