i've got a 4510R with a sup V, recently he started to restart non stop after entering the modules into an online state.
making the switch boot without startup conf delayed the restart for a while. it seems that entering commands cause the switch to restart, like a buffer overflow.
important to mention is that the status LED on the sup is ORANGE
have sent you the output. let me know if you had received it. it has all the required things tht you hvae to do,with some best practices.... hope this helps. if so, let us know..
