Dear XXXX
I bought a 3550 Switch of e-bay for my home lab, I have powered it up and if I issue a "sh IP int brief" command I only see one vlan interface an none of the fastathernet interfaces comes up.the IOs Image curreently is
c3550-i5q3l2-mz.121-13.EA1a. I want to know if the software image is corrupt or if the switch is damage. Can some one maybe give more in formation ?
I would be glad!
Thanks

If it is EMI you should be able to create multiple vlan interfaces on it ie.
int vlan 10
ip address 192.168.5.1 255.255.255.0
All new vlan interfaces will stay down until you allocate a port that is up into that vlan or you set up a trunk to another switch.
You may also need to issue the command "ip routing" on the 3550.
As for the fa interfaces. They will be down until you attach something into them.

Hi Jon,
Thanks for the qiuck reply,I know the fa/int will come up , but they don`t even show up in a "show run" command. There is nothing just 1 vlan interface, I can create mor vlan interfaces but thats about it.

Ahh okay i misunderstood.
Have a look at the attached link for troubleshooting hardware if you haven't already seen it
http://www.cisco.com/univercd/cc/td/doc/product/lan/c3550/1214ea1/3550hig/35trbl.htm
There is a chance you have a duff switch.

Jon,
It looked like the internal power suplly has failed, cause the sytem light stays amber so I think that could be the problem,Would you know If I change the power supply with a 3500 xl could it effect anything?
Thanks for your help:-)
