We have (as long we're swapping horror stories) a building here with redundant power feeds from 2 different substations. Since you can't have both actually connected to each other, there is a room with Very Big Switch in it. In case of maintenance shutdown on one side, somebody must manually throw the switch. The first time powerco had to do maintenance it turned out nobody there knew they needed to call the building first. Which was just as well since nobody in the building knew to take that call. Or was certified to throw that switch. -- Dimitri Maziuk Programmer/sysadmin BioMagResBank, UW-Madison -- http://www.bmrb.wisc.edu -------------- next part -------------- A non-text attachment was scrubbed...
