Power on the systems

Power the system on in the following order:
  1. Expansion shelves
  2. Active node
  3. Standby node

Complete the following steps to power on the system:

  1. Connect power cables to each expansion shelf receptacle and attach the retention clips.
  2. Provide power to power on each expansion shelf. The shelves power on when plugged in. Ensure that each shelf power cable is connected to a different power source.
    NOTE Wait approximately 3 minutes after all expansion shelves are powered on before powering on the controller.
  3. Provide power to power on the controller. Amber fault LEDs should turn on for all four power supplies.
    NOTE The DD9800 system should be powered from redundant AC sources. This enables one AC source to fail or be serviced without impacting system operation. PSU0 and PSU1 should be attached to one AC source. PSU2 and PSU3 should be attached to the other AC source.
    1. Connect power cables to each receptacle and attach the retention clips.
    2. Ensure that each power supply is connected to a different power source.
