the relevant customer-supplied PDU and circuit breaker numbers. If power cables are not

verify that power zone A and power zone B are powered by a different customer-supplied
PDU.
3. Do one of the following to connect power zone A and power zone B in each bay. If
necessary, use the 15ft extension cords provided by Dell EMC.
l
For single-phase power: Connect customer-supplied PDU power cables to the Dell EMC
