This task will track the swapping of the PDU tower(s) in rack A3-eqiad.
The current PDU tower is malfunctioning, with a short having caused issues on both side B (wholly offline) and parts of side a (one circuit group of outlets has defunct outlets.)
Chris has onsite spares (2 dual-wide PDU towers with 48 ports per side) to test out and use for replacement in this rack.
== Maintenance Window Scheduling ==
Primary Date: Thursday, 2019-01-17 @ 07:00 EST (12:00 GMT)
Backup Date: Tuesday, 2019-01-22 @ 07:00 EST (12:00 GMT)
Estimated Duration: Up to 2 hours
=== Maintenance Window Checklist ===
The following steps must be met for this swap:
[] - all servers will need to be taken offline and powered down for the duration of the migration
[] - old pdu must be removed from the rack, new pdu installed, all power migrated over to it
The side B of A3-eqiad may also have had the circuit breaker tripped during the failure, and may require Equinix technicians to flip the breaker in the EQ circuit breaker box.
