Chapter 1 Product Overview
Hardware Features
To reset the router to the factory default configuration or to load a custom configuration file, follow these
steps:
Step 1 Turn the power on.
Step 2 Press and hold the Reset button until the system status LED begins to flash. Typically, this occurs within
5 seconds.
The router reloads itself after the startup configuration has been replaced with the new customer
configuration.
For the second method, the configuration file can be located on an external USB flash drive or on the
router's compact flash.
The custom configuration file must be named one of the following:
•customer-config
•customer-config.SN ?
where "SN" is the unique hardware serial number.
When the system attempts to load a custom configuration file, configuration files on a USB flash drive
have priority over configuration files on the router's flash drive and the "customer-config.SN" file name
has priority over the customer-config file name.
The priority for loading a configuration file is as follows:
1. usbflash0:customer-config.SN
2. usbflash0:customer-config
3. Router flash:customer-config.SN
4. Router flash:customer-config
If the router does not find a valid custom configuration file, the system aborts the process.
To reset the router to the factory default configuration or to load a custom configuration file, follow these

Step 2 Press and hold the Reset button until the system status LED begins to flash. Typically, this occurs within
5 seconds.
The router reloads itself after the startup configuration has been replaced with the new customer
configuration.
