Unmanaged Switch.

[Morty Mort]

Hello.

First computer thread...

At work we had a D-Link switch 1016D.

http://www.dlink.com/products/?pid=337

It was connected to 1 modem, 12 workstations and 1 server. The server acted like a DHCP server (or something like that). If the server failed or went down, noone could get on the net.

Now I sold this switch to a guy who claims it doesn't work. It was sold as we needed a 24 port switch, so it was a straight pull-out.

He has connected two computers to the switch trying to play some game. The "power" led lights up but no connectivity led. He gets messages like "network cable unplugged" on both computers.

So I say this isn't a router, it's a switch. It might need some interpretion.

But I don't really know. What is a switch. Why doesn't it work??? He has no modem or router or hub etc. connected. Just this unmanaged switch.

You need a whole load more info - is he using patch leads that are known to work?

He'll need to sort out TCP/IP - either static assignment or have one of the using internet sharing wizzard and stuff like that.

Not an easy problem to diagnose quickly.

Yeah as jenks says, because there doesn't appear to be DHCP on his network neither of the computers will be automatically assigned an IP address, Windows will have randomly generated one and (being that it's good like that) has probably either given them the same IP address, or ones on completely different subnets. It's been a while since I've set up a non-internet sharing network, but IIRC the IP addresses should be in the format 169.254.0.x and the subnet should be 255.255.0.0. As long as the x value is different but everything else is the same they 'should' be able to see each other no problem.

Thanks for quick replies.

He uses cat. 6 cables, and we used cat. 5E so that should be ok. He also said they were standard cables, no crossings etc. Don't know the correct term.

The thing I found strange, is that no connectivity leds lit up on the switch. He should take it to school tomorrow and try it.

I'm familiar with IP adresses, like 192.168.1.x and 10.0.0.x and so on. Will give him a call.

Sorry, I haven't much more info to give.
