Connecting The System To Power
Figure 6. Connecting Power to the System
Connect the system’s power cables to the system power supplies.
CAUTION: To prevent the power cables from being disconnected accidentally, use the plastic clip on each power
supply to secure the power cable to the power supply, and use the strap to secure the power cable to the strain-
relief bar.
CAUTION: For AC power supply, do not plug the power cables directly into a power outlet; you must use a PDU. For
optimal system functionality, a minimum of three power supplies are required.
Plug the other end of the power cables of the AC power supplies into a power distribution unit (PDU). For DC power
supplies, plug the other end of the power cables to a branch-protected DC power source.
NOTE: The power supply units must have the same maximum output power.
NOTE: AC and DC power supplies cannot be mixed in an enclosure.
