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 areas named above should not be affected if it has been properly configured for operation with power cords attached to both the “A” and “B” PDUs in its rack.

Equipment outside the areas named above should not be affected, independent of configuration.

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