How to check why C2950 rebooted?

[S Kumar]

I have a C2950 which got rebooted on its own. Can someone suggest what do I need to check to see why it rebooted?

Try a show version and look for something like last power-on crash or last power-on cold start.

Here is what I see in "sh version"

The switch lost power.

Appreciate your reply. I am not sure how that happened. All other devices connected to the same power source were up and running.

What does it mean by "Last reset from system-reset" ?
