I AM a Business Partner, I routinely setup new S8300, S8500, S87XX systems, reboot old ones, upgrade CM from older versions to newer versions, etc. Nothing scares me. Very rarely do I have an issue that requires someone onsite, most of the work I do, is done remotley via RDP or PCAnywhere to the clients network/LAN.
If your translation have been saved, and you don't have any major hardware issues going on, a switch reboot is not a big deal. Yes, you can try the various reset levels, but usually you need to go to "reset 4" anyway, before you get results. Again, it depends on how hosed up your switch is.
Also, the newer switches are running RedHat Linux, and just like a Microsoft operating system (XP / Vista), Linux can benefit from an occasional reboot (only if you are having oddball issues, there is no need to reboot willy nillie)
