3Com Switch find Uptime

We had another incident with our VoIP phones restarting on Friday. As part of my troubleshooting efforts I needed to be 100% certain that the POE switch providing power to our phone didn't reboot.

To start there is no display uptime command in the CLI. But if you run the display version command part of the output is "Switch 4500 PWR 50-Port uptime is 6 weeks, 5 days, 2 hours, 25 minutes". This is exactly what I was looking for!

It should also be noted that the web interface for the switch shows the uptime on the device summary page.
