Notice of plan to power down the switchboards that feed power to the following pods:.
    R6-PA
    R6-PB
    R6-PC
    R8-PA
    R9-PA (odd side only)
    R2-PA
    R7-PA (tape library)

Both entrance rooms (ER-1 and ER2) will also be affected.

The work will proceed in two stages, on two different days:

Power down the "A" side switchboard:
    Estimated Start: 8:00 AM Wednesday September 27, 2023
    Estimated End:  5:00 PM Wednesday September 27, 2023

Power down the "B" side switchboard:
    Estimated Start: 8:00 AM Friday September 29, 2023
    Estimated End:  5:00 PM Friday September 29, 2023

Tenant Impact
--------------------
There may be brief periods of time when we will ask everyone to leave the Computer Room for safety (e.g. when a switchboard is being powered up).

Computing, Storage, and Networking equipment in the pods listed above that has been properly configured for operation with power cords attached to both the "A" and "B" PDUs in their racks should not be affected.

Equipment in pods other than those listed above should not be affected, independent of configuration.

There is elevated risk for the entire Computer Room while the work is being done.

Description
-----
The switchboards that feed power to the Pods listed above will be powered down in order to reconfigure the power feeds to Pods 8A and 9A.  The switchboards will be powered down one at a time, so there will always be at least one bus with active power in all of the pods listed above

The A side power feeds In the Entrance Rooms will experience two brief outages, at approximately 8AM Wednesday and 5PM Friday, as we will be able to run them on an alternate power source.  The B side power feeds in the Entrance Rooms will be down on Friday 9/29 from 8AM through 5PM.
