Procedure
1. Confirm that the customer-supplied power cables are labeled and that each
label contains the relevant customer-supplied PDU and circuit breaker numbers.
If power cables are not equipped with labels, alert the customer.
2. Compare the numbers on the customer-supplied power cables for each EMC
bay to 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 EMC.
l
For single-phase power: Connect customer-supplied PDU power cables to
the EMC bay by connecting to the bay's AC input cables for power zone A
and power zone B as shown below.
