Powering on the racks

Before you begin

Procedure

  1. The mainline power cables were routed to source power when the system was assembled. Do not connect the cables to source power yet.
    Note: The mainline power cables provide power to the Model 983 UPSs from a customer power outlet or PDU inside or outside the customer rack. If the cables were not routed to source power, refer to Assemble the storage facility in a customer rack.
  2. Identify the method used to control source power to the mainline power cables:
    • Dedicated circuit breakers (if shared with other devices, confirm with customer that the breakers can be switched off)
    • Connecting and disconnecting the source power end of the cables
    Note: It is up to the customer whether shared breakers can be switched off to control the power source. If shared breakers cannot be switched off, control source power by connecting and disconnecting the source power end of the power cables.
  3. Confirm that power is available for both mainline power cables.
  4. If circuit breakers are used, switch the circuit breakers off.
  5. At the rear of the rack, connect the mainline power cables to input connector J10 of both UPSs. See Figure 1.
    1. At the rear of UPS loosen, but do not remove, the cable retention bracket screw Callout label 1 and lift up to remove the bracket Callout label 2. See Figure 2.
    2. Connect the mainline power cables.
    3. Reinstall the cable retention brackets.
  6. Connect the mainline power cables to source power. If circuit breakers are used, switch the circuit breakers on.
    1. Record the time the mainline power cables were connected _______________________.
    2. Wait 1 minute for the UPSs to stabilize and then continue to the next step.
