Selecting the proper AC power connection procedureThe EMC Customer Engineer must select the proper AC power connection procedureThere are three possible scenarios at the installation site regarding the connection ofcustomer AC power to the EMC array. The EMC Customer Engineer (CE) must selectthe proper AC power connection procedure for the scenario.1. Refer to table below which summarizes the three possible scenarios at theinstallation site when you are about to connect external AC power to the EMCarray.2. Select the procedure that applies to your situation and follow the instructions forthat procedure.Table 38 Procedure options for AC power connectionIf the scenario is... then use this procedure:The customer’s electrician is available at the installation site. Aa, See: Procedure A: Working with the customer's electricianonsite on page 114Access to customer-supplied, labeled, power cables (beneathraised floor or overhead).(And the customer’s electrician is NOT available at theinstallation site.)B, See: Procedure B: Verify and connect on page 125Customer-supplied PDU source cables are already pluggedinto the EMC PDU (or VMAX 250F PDP) and you have noaccess to the customer-supplied, labeled, power cables(beneath raised floor or overhead).(And the customer’s electrician is NOT available at theinstallation site.)C, See: Procedure C: Obtain customer verification on page126a. Procedure A assures fault tolerant power in the EMC array.Best Practices for AC Power ConnectionsSelecting the proper AC power connection procedure 113
