If this is genuinely a brand new 2960L then there will be no configuration on it - other than the defaults which doesn't include any passwords or user credentials. Assuming you have connected via the console it should prompt you for its initial configuration - most people at this point just say no and then go for 'conf t' to configure it manually.
If you booted it up attached to a network then its possible that its obtained an IPv4 DHCP address, PnP has kicked in and its downloaded a default configuration from a a TFTP server (or possibly FTP or HTTP if Option 43 has been configured on the DHCP server). This is the basis of DNA LAN Automation if you're interested... If this has happened then whoever set the backend stuff up (DHCP, TFTP etc) should be able to point you to a 'cisconet.cfg' or similar file (there are a few filenames the Cisco PnP devices will attempt to download from a TFTP server) that may contain the base config. I use this all the time in the lab as it speeds initial builds up.
If it wasn't brand new and someone has applied some configuration to it then you can always do a factory reset. Just do a search for Catalyst 2960 factory reset. It involves holding the mode button (I think?) down and powering it on until something appears on the console. Its a very easy and I've recovered probably hundreds of Catalysts over the years using this method.
Good luck
