Switch A in UHB basement

One of the two Cisco 6509 switches in the basement of UHB lost power yesterday (Sunday May 22 @ 1:37PM). This switch did not restart correctly and required a manual restart on Monday. It was up and working at 8:36am Monday morning.
Not sure why the switch lost power or if that was what really happened. The switch is connected to a working UPS and the UPS was powered up and running.

We did discover that one of the Domain controllers is located in UHB connected only to the A 6509 switch. Any applications of services which had that specific DC unit selected for identification failed. The ARC attendant console was one such application, and some of the webmail servers were trying to use this DC unit and failed.

    Thanks for the report, Jamie. This points out a need to ensure that all dependent systems point to a load-balanced, fault-tolerant IP address, not to a specific server.
