Power Cord Routing
The drive module and command module use two AC power cords (one for each power supply). You must have an independent AC power source for each power supply in the drive module and command module in order to maintain redundancy. This applies to both deskside and rackmount models.
Some rackmount cabinets have two AC distribution boxes. Each AC distribution box has its own power cord. To ensure redundancy, connect the AC boxes in the cabinet to two independent power sources. Then, connect one power cord from each drive module or command module to each AC box in the cabinet (Figure 5). Because of limited space inside the cabinet, it may be easier to connect and route power cords before installing the support rails and drive module (or command module).
