On 30 August 2016, between 08:00 and 14:00, the SDSC Datacenter will undergo the first of two outages necessary to upgrade the CDS2 power system. In order to accomplish this upgrade, many datacenter racks will be temporarily powered off, or lose one leg of power within the rack.
List of racks that will be powered off during the outage window:
T-BB18, H18, K18, DD-KK31, S-V36, BB36, AA39, HH-KK39, R-HH44, E-HH47, X-Z52, BB52, S-BB55, R-DD60, K-T63, EE-FF63, R-DD68, X71, AA-CC71, K-P77, R77
Racks that will lose power redundancy:
N-Z26, N-Z29, U-CC63, Networking core row 77
When power is returned on the afternoon of Aug 30, all of the power legs served by CDS2 UPS backup power will be served by street power only. A subsequent outage in 5-6 weeks will reconnect a new UPS system.
