Procedure B: Verify and connect
Perform this procedure if the two conditions listed below are true:
Access to customer-supplied, labeled, power cables (beneath raised floor or
l
overhead).
The customer's electrician is not available at the installation site.

This procedure requires the EMC Customer Engineer to verify that the customer's
electrician has complied with power specifications. Once verified, the 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 36
on page 115 and described in Procedure A, Task 2.
3. 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.
4. If power extension cables are required, connect them to power zone A and
power zone B in each bay.
5. Connect the customer-supplied power cables to EMC power zones as described
in Procedure A, Task 2.
6. Record the customer-supplied PDU information as described in Procedure A,
Task 2.
7. Label the PDUs as described in
Best Practices for AC Power Connections
PDU labels
