This activity will cause an interruption of all the networking in Hall D, which means that CODA DAQ , EPICS or anything that requires networking will be down. Preliminarily, this work is scheduled to happen on Monday, May 9 at 1pm. At that time all switches and routers will get rebooted which will take about 15 to 20 minutes and no networking will be available during this time. Afterwards, the settings on the switches will be modified which should not cause outages but may cause instabilities. The whole procedure is expected to be completed within two hours. <o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>If you have a planned activity at that time that cannot be postponed and will be impacted by this network outage, please let Sergey or myself know by this Friday, 4pm so that we can reschedule it. <o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>Best, <o:p></o:p></p><p class=MsoNormal> Hovanes. <o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal><span class=DefaultFontHxMailStyle><span style='font-size:12.0pt'> </span></span><o:p></o:p></p><p class=MsoNormal><span class=DefaultFontHxMailStyle><span style='font-size:12.0pt'><o:p> </o:p></span></span></p></div></body></html>
