This task will track the migration of the ps1 and ps2 to be replaced with new PDUs in rack [[ https://netbox.wikimedia.org/dcim/racks/16/ | B8-eqiad ]].
Each server & switch will need to have potential downtime scheduled, since this will be a live power change of the PDU towers.
These racks have a single tower for the old PDU (with and A and B side), with the new PDUs having independent A and B towers.
[] - schedule downtime for the entire list of switches and servers.
[] - Wire up one of the two towers, energize, and relocate power to it from existing/old pdu tower (now de-energized).
[] - confirm entire list of switches, routers, and servers have had their power restored from the new pdu tower
[] - Once new PDU tower is confirmed online, move on to next steps.
[] - Wire up remaining tower, energize, and relocate power to it from existing/old pdu tower (now de-energized).
[] - confirm entire list of switches, routers, and servers have had their power restored from the new pdu tower
