This task will track the overall upgrade of racks in rows A and B (other than b5-eqiad, which was already upgraded via T223126). All of the PDUs on this task were ordered via T223461.
Please note that of the 15 sets of PDUs, two sets are for the networking racks and have special flexible power sockets for the C19 requirements for the MX480s.
Since each rack will have a checklist of servers unique to that rack, this task will simply list each of those sub-tasks as they are created.
Every attempt will be made to ensure hardware with redundant power doesn't lose power entirely, and should be able to migrate without downtime. However, mistakes happen and due to cabling constraints, accidental power loss may occur.
Scheduling: Upgrades will continue based on the following schedule below, between Sept 10 - Nov 4, targeting Tuesdays and Thursdays (one rack per day) at 11am UTC (7am ET)
