If the switch is Cisco, post the complete output to the following commands:
1. sh version; and
2. dir

It is very difficult to determine unless I see the output. I want to see if the switch crashed or had a reboot. If the switch crashed, is there the presence of any evidence of a crash.

Without those information I can't even begin to know where to make a guess.

You've mentioned both a DX80 and an SX80 in your question - can you let us know which one it was, as they are quite different and could cause a different set of issues depending on which one it is:

ie if it's a DX80, then you could have created a loop on the network, or if it was a SX80, then you have possibly connected an additonal DHCP server to your network which could conflict with other devices. Either way, it's unlikely that the whole switch would have gone down.
