HP procurve transciever modules, what do they do?

[Chronictank]

A bit of a newbie question, on the front of my procurve 2524 there are 2 slots for transciever modules. My switch came with a fibre module and I just guessed it was for stacking switches, but could someone please confirm what they are for?
Could I buy a gig Ethernet one to plug a server into? If i could would the increased bandwidth the server make a difference for things like deploying OSs to multiple clients simultaneously over the network?

Thanks

They are simply slots for holding connectivity modules.

You can use a fibre-channel card in a server and directly attach to the fibre module in the switch if you like.
