Cabling power supplies for power feed redundancy

Power feed redundancy may be achieved by connecting 1+1, 2+2, or 3+3 power supplies to Phase A+B. To cable a frame for power feed redundancy, use the following recommendation as a best practice:

  1. Connect power supplies 1, 2, and 4 to the A-side power distribution unit.
  2. Connect power supplies 3, 5, and 6 to the B-side power distribution unit.
    Connect power supplies to redundant power sources
  3. Verify that the power supply cords are securely connected using the reusable cable tie wraps.

After power is supplied to the frame, it powers up automatically. The power and health LEDs on the front panel, Composer appliance, and frame link modules illuminate green to indicate that there are no errors or alert conditions.
