This procedure requires the Dell EMC Customer Engineer to verify that the customer's electrician has complied with power specifications.
Once verified, the Dell EMC Customer Engineer makes the required power connections overhead or under the floor.
NOTE:
Utilize proper strain relief methods when customer-provided power drops are located overhead or wall-mounted.
Steps
1. Have the customer verify that their electrician has complied with power specifications for voltage levels and redundancy. If the
customer cannot verify this, provide them with a copy of Procedure A. Inform the customer that their array may prematurely shut
down in the event of a site power issue.
2. Access the labeled, power cables (beneath raised floor or overhead) to verify that the customer-supplied power cables are properly
labeled as shown in
Figure 29. Circuit breakers OFF — No AC power
on page 64 and described in Procedure A, Task 2.
3. Compare the numbers on the customer-supplied power cables for each storage bay to verify that power zone A and power zone B are
powered by a different customer-supplied PDU.
4. Connect the customer's PDU AC cables to the storage bay power zones as described in Procedure A, Task 2.
5. Record the customer-supplied PDU information as described in Procedure A, Task 2.
6. Label the PDUs as described in
on page 70.
