Try this http://www.cisco.com/c/en/us/suppor...950-series-switches/12040-pswdrec-2900xl.html for password recovery
as for the one bank not working, do the led lights work when you plug a device in?

Once you've managed to get in - check running config that there isn't a port group shutdown

yes, the switch usually has port to asic mappings.
I am too lazy to look up the mappings on a 2960, but it is possible that they bank 12 ports per asic as it is an entry level switch.
Which means if the asic fails, you will lose those 12 ports

/EDIT/ type sh platform pm platform-bloc look for the asic column, this will tell you which asic is used for which port.
on the 48 port it breaks it up into 2 asics, not sure on the 24 port

Yup could also be this - but considering he can't access the CLI yet, I'm assuming a previous config

No LED lights on that bank only
