I've just got a Dell PowerEdge T610 server. The case is locked and looks like it needs a flattish key to open. Two circular ended keys came with the server, but they fit the front of the case, not the side.
Is there a trick to it, or did I get the wrong type of key with it?
Watch this YouTube unboxing video. The key is attached inside the front bezel. He uses the round end of the key to open the side panel @2:30.
Generally Dell servers dont need a key, the part that looks like it needs a flattish key doesn't take a key at all - a small coin will do it.
