Power cord connection

Overview
Connect a power cord from each PSU on the enclosure rear panel to the PDU (power distribution unit) as

shown in the figure below.

Figure 24. Typical AC power cord connection from PDU to PSU

Important: The Disk Enclosure is fitted with two redundant PSUs. All power cords must be connected to

at least two separate and independent power supplies to ensure redundancy.
• The figure above shows the power connection from a single-core PSU to a PDU using C19 connectors.
• The C20 plug on the PSU connects to the C19 receptacle of the power cord. The C20 plug on the power

cord connects to the C19 receptacle in the PDU.

CAUTION: Power connection concerns:
• Never connect the power cord to the PSU before installing the PSU in the system.
• Always remove the power connections before you remove the PSU from the enclosure.
• Whether standard (single-lead) or bifurcated (Y-lead), power cords must only be connected to a

supply range of 200–240V AC as indicated on each PSU’s hazardous voltage warning label.

Testing enclosure connections
See the section “Powering on/powering off” on page 45. Once the power-on sequence succeeds, the

storage system is ready to be connected.

Grounding checks

The product must only be connected to a power source that has a safety electrical earth connection.

CAUTION: If more than one enclosure goes in a rack, the importance of the earth connection to

the rack increases because the rack will have a larger Earth Leakage Current (Touch Current).

Examine the earth connection to the rack before power on. An electrical engineer who is qualified to the

appropriate local and national standards must do the examination.
