RTFD: Reset To Factory Defaults

Top of Rack (TOR) switches sometimes require reconfiguring. It is difficult to reset and erase a TOR switch in the field. The process can be long and tedious with the user needing to log into the switch using the serial port and issuing a number of commands to manually erase areas of memory. This method is prone to error.

Reset To Factory Defaults (RTFD) is a simple and reliable method for resetting a switch to factory defaults. The process has evolved over time. The initial switches required the operator to press and hold the reset button during the initial boot up memory test. This required the serial port to be connected. A Complex Programmable Logic Device (CPLD) was added on all TOR switches after the development of the initial switches, to be able to accurately time how long the reset button was being pushed. This also helped eliminate the need to have the serial port connected to do this.

Now, if the user of the switch holds the recessed reset switch for more than five seconds, the switch automatically resets to factory defaults. This allows a previously configured switch to easily be wiped clean and be ready to re-use as if it is a brand new switch.
