Install an 1100 W Internal DC Power Supply

The ExtremeSwitching X690 and X870 series switches accommodate one or two Summit 1100 W power supply units (PSUs) with either front-to-back or back-to-front airflow.



You cannot combine power supplies of different wattages in the same switch.

  1. Make sure you have the tools and materials you need.
  2. Prepare the power cables and ground cable by attaching the provided connection lugs to the cables.
  3. Insert the power supply into the switch.
  4. Connect the ground wire.
  5. Connect the power supply to the electrical source and energize the DC circuit.
