We will be replacing defective hardware on the HP 4108GL switch in ESB building in order to proceed with a firmware upgrade on all switches in ESB. This will cause a temporary  downtime for the ESB network next Wednesday, October 26, 2011. We are scheduling a window from 06:00 am to 07:00 am, however, we anticipate the work to take less time. During this window all network traffic within ESB will be disconnected.
