This task will track the migration of the ps1-eqiad and ps2-eqiad to be replaced with new PDUs in rack [[ https://netbox.wikimedia.org/dcim/racks/1/ | A1-eqiad ]].
Each server, switch, and router will need to have potential downtime scheduled, since this will be a live power change of the PDU towers.
The network racks have two individual PDU towers existing, and will be replaced with two new PDU towers, so this swap is easier than the majority of the row A/B PDU swaps (with their combined old PDU towers.)
[] - schedule downtime for the entire list of switches, routers, 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
