How to reset a Cisco 3548XL-EN to factory settings

I purchased a Cisco Catalyst 3548XL on Ebay as I begin to prepare for my CCNA Exam.  The seller doesn't have the username and password for the switch so I want to reset the switch to factory settings so I can start using it.  Can anyone provide me with details on how to do this?  TIA.
