Bro.. I have been working as web system engineer( hired as a weblogic Admin-a kinda system admin..not really) for around some time now... i strictly work on servers, i deploy the codes,build the new environments, and troubleshoot the issues that i get within the servers and environment. Admins are not supposed to go and look into the code, if you have knowledge, that fine but developers are there to do that. but the interesting thing about admin postion is that you are right in the middle of all people, developers,database admins, QA and networking so you need to communicate accordingly and make good relations with everyone..that might come handy.. from your story, i do not feel any kind of panicking situation..that happens all the time.. i even do not sit close to my manager, my cube is in next building to my manager... so dont worry brother..keep calm and work. all the best.
