Power distribution units
CAUTION:
Dell EMC PDUs are designed to be mounted securely in Dell EMC racks. They are not intended for third party
racks.
PowerMax systems are powered by two redundant power distribution units (PDUs), one for each power zone. The PDUs are available in
three wiring configurations:
•
Single-phase
•
Three-phase Delta
•
Three-phase Wye
The AC power cords (single-phase and three-phase) extend above the bay egress for connection to the customer power supply. 15ft
(4.57M) power cords that plug into the bottom of the PDUs are provided. For single-phase, more than one power cord per power zone
may be required.
The AC cords can be routed out either the bottom or the top of the rack. If the customer requires power to be supplied from overhead,
Dell EMC recommends replacing the rear top cover of the bay with the ceiling routing top cover, which allows the power cables inside the
machine to be routed out through the top.
A second option is to "drop" the power cables down the hinge side, to the bottom, and route them inside the machine. The cables should
be dressed to allow all doors to open freely and space should be provisioned accordingly to accommodate an adjacent cabinet.
If the customer requires power to be supplied from overhead, the Overhead Routing Kit is available to route the power cables inside the
machine through the top. Extension cables are not provided. See
on page 60 for information on optional kits.
NOTE:
Utilize proper strain relief methods when customer-provided power drops are located overhead or wall-mounted.
Power interface
Data centers must conform to the corresponding specification for arrays installed in North American, International, and Australian sites.
Customers are responsible for meeting all local electrical safety requirements.
Customer input power cabling
Before the array is delivered, the customer must supply and install the required receptacles on their PDUs for zone A and zone B power
for each system bay.
Dell EMC recommends that the customer's electrician be present at installation time to work with the Dell EMC customer engineer to
verify power redundancy.
