Newbie question - What's wrong with my switch? open original image

Newbie here trying to set up a CCNA lab. A friend gave me a Catalyst 3550 but it's not fully working. I'd like to use to become familiar with switches first before going to routers (I have two routers but can't get the DCE cable to hook them back-to-back Anybody know how to make a male DTE cable into a DTE cable? I have a soldering iron:)



When I power up this switch the Systen light stays amber - which I hope I know means that the post test did not pass.



I also know from the outpt listed here below that Ethernet Controller (2) is bad.



Any help in identifying and trouble shooting the problem would be welcome.



Thanks.

At $2 of so on eBay, vs. probably 10 hours of your time making it, wouldn't it be easier to buy one on ebay for your DCE to DTE cable? Those DB60 connectors are murder to hand solder..

Umm, the problem is that you have fried hardware, and fixing it will most likely involve unsoldering highly dense surface mount chips, finding said chips in the repair channel to be able to even buy them, and reflow soldering them back on?

The switch probably functions for the first 12 ports and the last 2, just not for ports 13 to 24?

The 2nd bank of 12 ports is probably fried beyond most people's ability to repair for even 10 times what Smartnet would cost to get it repaired (since the limited lifetime warantee isn't going to apply to you).

I'd recommend Dantrak from eBay for cables. They are top notch and great to work with. I agree about not hand soldering those things.

for back 2 back cables. I have had dozens of these over the last few years and never a problem. Great price too.

Thanks for the link Andy. Would a DB60 to DB60 Crossover work ? There are so many cables listed that I am a little bit confused as to which one is the one I need....

The Catalyst 3550 ended up in the garbage where it came from - I don't have time to fool around with defective equipment wondering if it's me who's doing something wrong - maybe at a later time when I gather some experience with these boxes...

Thanks for tip James.

Yeah, it ended up in the grabage - will try to get me another switch - it's no good to try to learn on something that is broken...
