Complete the following steps to attach the power cords.
1. Wrap the strain-relief clamp around the power cord approximately 20 cm (8 in.)
from the power supply connection end.
2. Attach the power-supply nut, and tighten it securely.
3. Connect the power cord to the power supply.
4. Plug the power cord into a properly grounded electrical outlet.
Note: To maintain power redundancy on the DS4300 dual-controller storage
server (Model 60U/60X), plug the storage server’s right and the left
power supplies into two independent external power circuits through ac
distribution units inside a rack cabinet or directly into external
receptacles. Similarly, the right and left power supplies of the DS4000
storage expansion enclosures attached to the DS4300 storage server
should be plugged into the same two independent external power circuits
as the DS4300 storage server. See Figure 40 for an example of
redundant power cabling.
Exception: The DS4300 single-controller storage server (Model
6LU/6LX) has only one power supply, so it does not support power
redundancy.
