Perform this procedure if the two conditions listed below are true:
l
You have access to customer-supplied, labeled, power cables (beneath raised floor
or overhead).
l
The customer's electrician is not available at the installation site.
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.
Procedure
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 3 on page 17 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-supplied power 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 Applying PDU labels on page 25.
