All systems must be wired so that AC lines feeding blue AC boxes and AC lines feeding orange AC boxes are sized to support the entire system load.

Teradata power subsystems use load sharing by default. Sites can expect an approximate increase of 100% in load on the active line when the other source of power fails. That is, a source has 50% of the load to start with, and when AC is lost from the other source, the remaining 50% of the load transfers to the active source.

Products with four cords need special attention when plugging in at sites with redundant power to ensure proper operation if one power source fails.
  • If the cabinet uses four cords and has orange and blue AC boxes, the two orange cords go to one site source, and the two blue cords go to the second site source.
