Thank you -- I was able to get the printers working!
Back again with a new question... I recently inherited our network at a small college prep private boarding school.  The network was configured by an outside company many years before I arrived.  There is little documentation (that I know of), so I am flying a bit bind here. I recently replaced an old 3348p with a 3548p, and got out IP phones and Internet working, but network printers are out. I am assuming I need to configure the port(s) to which the printer(s) are connected -- any tips that will help a newbie? Thanks Tim
