Setting up a New Network with a static ip DSL line and a managed switch no router.

We'll soon be moving into a new office building and with that gaining access to a DSL hookup with a static IP.  I'm a novice when it comes to networking.  I need to know if I'm missing something here or not.  We have an, AS/400 (iSeries) server, a managed switch (Dell Powerconnect 3348 new), 15 PCs, and a DSL modem.  Do I need a router with this type of switch?  If not, where do I plug in the DSL modem to, in odrer to let all 15 PC's have access to the internet and not let the AS/400 have access but still be available to the PC's

Our network structure to start off was planned to look like this:

15 PC's ------- Patch Panel ------ Switch ------ DSL Modem ------ Internet
Zone Alarm Pro

In one month I'll be introducing a Windows SBS 2003 Server so I imagined the structure of the network would become:

15 PC's ----- Patch Panel ----- Switch ----- Windows Server ------ DSL Modem ----- Internet
                                                        Software Firewall Included

Can you guys help me out?

You will need a router for your configuration to work.  Since you are sharing the internet connection, you need NAT performed.  The Dell switch although has some layer 3 capabilities will not perform NAT (not sure if it routes at layer 3 also).  You need to buy a DSL broadband router and connect that into your switch along will all other devices on the network.  The DSL router will take care of NAT and also DHCP for your devices on your LAN.  So your network would look like this:

15 PC's ------- Patch Panel ------ Switch ------ DSL Router-----DSL Modem ------ Internet
Zone Alarm Pro

The DSL router is pretty much plug and play so you shouldn't have a problem setting it up.

Many vendors make DSL broadband routers, such as Linksys, D-Link, and Netgear and cost around $50.

Also, nobody will be able to get to the AS/400 from the internet...

Then how does the router connect to the switch?  Through one of the 48 ports?
