Notice of plan to power down the switchboards that feed power to Pods R3-PA, R4-PA, and R5-PA to work on computer room switchboards.

Estimated Start: 8:00 AM Tuesday October 4, 2022
Estimated End:  noon       Tuesday October 4, 2022

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 pods R3-PA, R4-PA, and R5-PA 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 R3-PA, R4-PA, and R5-PA 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 Pods R3-PA, R4-PA, and R5-PA will be powered down in order to install new electrical circuits in the MGHPCC computer room.  The switchboards will be powered down one at a time, so there will always be at least one bus with active power in all three pods.  Each switchboard will be powered down for two days.
