The server rack was built to fill from the left bay first, one column of blades at a time, following the cooling airflow path. The spec mandated that in any capacity reduction, the most recently installed column — the rightmost, farthest from the intake — be decommissioned first, since those blades ran hottest. When the power budget was cut, the ops team followed protocol: the last column went dark while the rest kept running. The budget was restored the following quarter.
