Dispatches From The Geeks

News and Announcements from the MCS Systems Group

Building 221 Emergency Power Outage, Saturday April 5, 2008, 6 AM to 6:30 PM

Emergency maintenance needs to be conducted on the power distribution panels on the service floor of Building 221 tomorrow.  The outage window is 6:00 AM until 6:30 PM.During this time, building 221 will have no power, including all offices and desktop computers, as well as the machine rooms.All machines in the MCS machine rooms will be down, with some exceptions.  The machines that will be down (aside from any systems already down) include all clusters, BG/L, TeraGrid, and full-disclosure (the SiCortex).Network connectivity will stay up, as will machines in our Tier One service rack, including the file servers and web server.  Mail service will be down, though all mail will still be delivered, just delayed.We apologize for the abrupt notice on this — it’s related to the power situation we’re facing in the machine room, but has a broader scope than that.  If this work is not done, any panel could go down and stay down until this work is done.  Specifically, the mechanisms that house the large main breakers on the distribution panels are not working, which means no tripped breaker can be re-seated.Thanks for your understanding.
