My first Arduino attempt

I just gave it my first shot to get something arduinie alive. The outcome was ok however I am still stuck with no doubt some beginners issues.
Well first arduino I tried failed, the L1 led blinks but it does not like an upload, so tried another one this worked. I upped the info from the site http://blog.lvivier.info/
Which is an application to cobine and arduino with a conrad dcf77 clock, to output Meinberg compliant data for NTP. So adding the sketch and waiting until the rig was in sync produced the result I wanted to have. I could sync a server with a dcf77 clock. Next would be to build this into a box and make it permanently connected to the server. But as I had a stck of arduino shields around I wanted to tweak this setup which I guess for a beginner might be to much..... So I added an ethernetshield IE Shield 1.1, also a serial LCD to complete it.
Next after stacking my shields tested it again, to have it working as it did before. To bad the USB connection got lost. First I blamed the USB power, but I found out hooking up the Ethernet shield is enough to break it.
My question is what's up with the ethernet shield, do I need to configure an code it before I can plug these in ( when I am not suing it yet) ? because I am aware my knowledge is currently limited so I wanted to build the NTP server and for now use USB to link it, in future I want to make an NTP server out of this generating time signals for ethernet which can sync the entire network. I would of course besides the answer to my question also welcome any info that might help to get this idea realized.

Thx.

Depends on which Ethernet shield you have. The official ones do not need to be removed. Some crappy ones from EBAY apparently do need to be removed. You get what you pay for.

Well, possibly more correct to say that ethernet shields with built in PoE need to be removed for arduino programming. Has it been documented that an "official" ethernet shield with PoE (if there is such a thing) can be programmed without removing the ethernet shield?

Possibly. But then "Power over Ethernet" and "My first Arduino attempt" really don't belong on the same post.

"My first Arduino attempt" and "But as I had a stck of arduino shields around I wanted to tweak this setup which I guess for a beginner might be to much.....

Funny, but true.
