Hello.  The large fraction of our machines in RCF will go down on this 
Thursday due to the power distribution maintenance.

Hiro

attached mail follows:


Plant Engineering needs to move PDU W to a new feeder circuit,
as part of the plan that will allow the installation of the
new robot and the redistribution of power for other new 
equipment in FY06. This will involve a 1-hour downtime for 
PDU W on Thursday, Jan. 12 beginning at 10 am, which powers 
the following systems on 4 racks:

BRAHMS: rcrs0044-0051, rcas0039-0068
PHENIX: rcrs2186-2243
PHOBOS: rcrs4385-4416

In preparation, we will close all Condor queues at 10 am and 
all interactive access (BRAHMS) by 6 pm on Wednesday, Jan. 
11. The racks will be powered down at 9:30 am on Thursday,
and all remaining jobs and interactive sessions will be 
killed.

I plan to make a general announcement later today (Monday).
Please let me know if you feel the timing of the pre-shutdown
preparations need to be adjusted.

Tony
