I say "security" because I know that in a shared space, nothing is completely secure. I also know that with enough intent, someone will accomplish whatever they set out to do regarding breaking something of someone else's. My concern is mainly towards mitigation of accidents. This could even apply to a certain degree to things within your own space and your own careless techs If you have multiple entities in a shared space, how can you mitigate the chances of someone doing something (assuming accidentally) to disrupt your operations? I'm thinking accidentally unplug the wrong power cord, patch cord, etc. Accidentally power off or reboot the wrong device. Obviously labels are an easy way to point out to someone that's looking at the right place at the right time. Some devices have a cage around the power cord, but some do not. Any sort of mesh panels you could put on the front\rear of your gear that you would mount with the same rack screw that holds your gear in? ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com
