Configuring Switch

epidemik · 05-26-2008, 10:27 PM

The IT at my school gave me 2 (cause theres a decent chance their broken) old 3Com 1100 24 port switches and said they'd work for a small LAN.

I dusted them off and didnt know where to begin. I cant even tell if they work or not. Id dont want to do anything fancy, just set it up for a lan party.

Pretty much, where do i plug the internet into?
and how what else do I need to do to configure them?

Also, how can I tell if theyre broken.

I tried reading manual but it went over my head.

using a switch is fairly simple. If you want it to get connectivity, what i do,Depending on what switch you have is I take a Ethernet cable that is plugged into my router and plug that into slot 1 on the switch with gives it internet. After that all you need to do is plug another Ethernet cable from your computer to the switch. I guess the only way to check whether the switch works would be to get it hooked up and everything and check each port separately.

Cool, ill try that. I wasnt sure where to plug in the ethernet cable thats plugged into the modem.

Question: Does it go Modem -> Switch or does it need to go Modem -> Router -> Switch?

Try:
modem -> router -> switch -> PC,

Just so you get DHCP IP addressing from the router. without the router you might run into problems. You might want to download the manual for the switch incase it has a strange Static IP address. if you find that you cant access the switch, do a Full reset and access the switch (should be a web access or telnet) set the IP address to Dynamic DHCP if its not already and you should be ready to rock and or roll.

With mine, i go Modem>Router>Switch>PC, my modem and router are upstairs, i have an ethernet running down through the walls and plug it in from down here. With my isp, it won't let me just go modem>switch, get some dumb error so, your best bet is Modem>Router>Switch>PC

To be honest, managed switches such for home networks. In fact they are only good in all honesty for large networks, when you need to set up specific VLANs or what not.

When I mass netboot and reimage machines, I don't do it on our managed switches, too much over head. Instead I get dumb switches and use them. The down side is they don't support port fast so it takes a few seconds longer to get an IP from DHCP, but other than that it is the way to go.
