Powering on the racks

Before you begin

Procedure

  1. Complete steps 2 - 5 for Rack-1, then repeat steps 2 - 5 for each expansion rack you are installing.
  2. Remove the lockout tag and/or device that was applied to each customer mainline AC voltage circuit breaker, then switch on the customer circuit breaker.
  3. Switch on both customer circuit breakers for this rack.
  4. At the rear of each rack, switch both CB1 main line switches to On (up).
    1. Record the time the Rack-1 CB1 main line switches were set to On _______________________.
    2. Wait 2 minutes for the DC-UPS to stabilize and then continue to the next step.

  5. Observe the LED indicators and digital status display at the upper right (single-phase) or lower right (three-phase) of both DSUs. Use Table 1 to find the condition that applies.
    Note:
    1. Other LED indicators might be on or flashing (for example, J1-1 DDM). For this step, we are concerned only with the LOCAL AC and DSU SERVICE LEDs and the digital status display.
    2. Storage enclosures and high-performance flash enclosures will not be powered on at this time. For certain models, only some (but not all) high-performance flash enclosures will not be powered on at this time. This is normal. They will be powered on later as part of the storage facility field installation process.

    On Off Blank Normal condition, continue with the next step.
    On Off Two-character status code other than Blank. Go to MAP21A1 DC-UPS fault isolation during installation.
    Off Off
    • Blank (if both DSUs in the rack have loss of input power or both have input phase setting misplugged)
    • I1 (on affected DSU, if only one DSU in the rack has loss of input power)
    • Three-phase: Check the DC-UPS input phase selection setting on both DC-UPSs. Ensure that they are the same. If the setting does not match the customer power type, the DC-UPS will not power on and will not be damaged. Refer to Checking customer power type and DC-UPS input phase selection settings.
      Note: If the customer power type is three-phase high voltage (380 - 415 V), you must use the provided five-wire mainline power cables. If four-wire mainline power cables are used, the DC-UPS may need to be replaced.
    • Single-phase, and three-phase with correct input phase selection: Customer input power fault, see MAP2051 Loss of AC Input to a single DC-UPS DC supply unit (DSU)
      Note: If both DC-UPSs are failing, then repeat the customer voltage checks done previously.
