Over the years, I have come across numerous challenging technical situations that have surprisingly very little information after Google searching and scouring IT discussion forums. TEKinaka.com has articles that have been pieced together by my experiences and are in no way designed to be a “fix all” for every problem you might be faced with. However, after hours of banging my head on the wall, it’s worth having something documented here that I can refer back to down the road. If it helps another person in the process, then its even more worthwhile. I hope you find these entries useful, informative, or at least thought provoking enough to kick start a troubleshooting process that gets you to a solution.

Upgrade Firmware / Bootloader on Cisco SG300 / SG500 SwitchesAaron
