Have a look at this link. You don't say what you actually but you can have 1x1Gbps, 1FE or 2FE ports. Click on the links next to each card and it will tell you in that doc how many cards you can put in each model of router and what IOS is needed -

If your need is for another Fast or Gig Ethernet port, and if you're already connected to a VLAN capable switch, you might consider using subinterfaces on an existing 2821 port to a trunk port on the switch.  Saves you the cost of the extra Ethernet port module, plus considering the 2821's limited performance, you'll likely not be able to actually fully use the bandwidth of it either.
