Facility Services will be testing emergency power in Hamilton Hall at 7:30 am on Wednesday May 4th. This will affect the UPS (i.e. battery-backup unit) which gave us trouble on May 2nd and April 15th - and we can't trust this unit to coast thorough the power interruption.
I'm going to perform a prophylactic shutdown of the systems on that UPS unit at 7:25 am. Everything should be up again at 7:35 am.
The main server will not be shut down, but mail and web will be unavailable because the mail file array will be.
Note the faulty UPS will be replaced in the next week or so; the replacement will require about 30 minutes of downtime.

We had a server-room power failure this morning - web, email and workstations were unavailable between 8:37 AM and 9:15 AM. Just as was the case on April 15th, the main server wasn't down put the main storage array was.
This second failure confirms that we have a problem with one of our battery-backup units; I will be replacing it ASAP.
