Last Friday, I replaced Chassis Power Regulator board D060279 with D1000217 on the following AA/AI Chassis.
 
S1102693
S1102694
S1202505
S1202506
S1102693
S1000250

This was to address overheating/over stressing of components on old power board.
The units are located in the SEI and SUS Test Stands in the staging building.
