This task will track the installation, setup, and transition to our new (WMF owned) PDU towers in our racks in ulsfo.
**This work is scheduled for Tuesday, December 18th, at 11:00-12:00 Pacific.**
Please note that datacenter vendor policies do not allow customers to pull floor tiles to (de)energize PDU towers. All sub-floor work must be done by DigitalRealty engineers. Due to that, this will be a multi-step process.
[x] - install ST B PDUs in each cabinet. This leaves the APC B PDUs unsecured (see photos in T209101#4811939), so only tower B of the servertechs will be installed in advance. This ensures we don't have 2 unsecured PDUs banging around in the cabinet (when the doors open, they move due to all the power cables.)
[x] - schedule DR engineering/tech time to work with @robh onsite for 1-2 hours and migrate entire racks at that time with the following steps:
[x] - DR tech energizes ST B PDUs in each rack (de-energizing APC tower B in each rack)
[x] - @robh moves all B side connections from APC to ST B PDUs in each cabinet
[x] - @robh removes APC B PDUs from cabinets to return to DR
[x] - @robh unsecures APC A PDUs in each cabinet and mounts ST PDU tower A in each cabinet
[x] - DR tech energizes ST A PDUs in each rack (de-energizing APC tower B in each rack)
[x] - @robh moves all A side connections from APC to ST B PDUs in each cabinet
[x] - @robh removes APC A PDUs from cabinets to return to DR
Remaining steps can be completed without DR support:
[x] - add brackets to ps1 in each cabinet
[x] - balance power between towers
[] - label and normalize each server's power ports (so if server X in is port 1 on one tower, ensure its in matching port 1 on the redundant tower) and update PDU software labels
[] - update netbox software port assignments to reflect pdu software
[x] - add pdus into monitoring
[] - connect ps1-23 to scs
