26 Drive Module Site Preparation Guide
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).
