Demand intimation from cpc

Hi,

 
I had filed my AY 12-13 ITR (ITR-1) by e-filing on 28th July 2012 and paid the relevant tax amount, which is reflecting in my 26-AS also.
 
On 15th Oct 2012, I received an e-intimation u/s 143(1) which showed that I had under calculated my taxes by approx Rs. 1150 and hence the same to be considered as a notice of demand u/s 156. 
 
Unfortunately, I did not understand the same then and took no action.
 
As on date - 26th July 2013, what action can I take? Can I simply pay the differential? Do I have to pay any penalty?
 
Also, my e-filing account shows the entire amount as outstanding tax demand (though what I paid is showing correctly in 26-AS). Do I have to do anything here?
 
thanks,
