Dell EMC PowerSwitch S5048F-ON Installation Guide December 2019

PDF

AC or DC power supply installation

NOTE: : The PSU slides into the slot smoothly. Do not force a PSU into a slot as this action may damage the PSU or the switch.

NOTE: : Ensure that you correctly install the PSU. When you install the PSU correctly, the power connector is on the right side of the PSU.

NOTE: : If you use a single PSU, install a blank plate in the other PSU slot. If you are only using one power supply, install the power supply in the first slot, PSU1. Install a blank plate in the second slot, PSU2.

  1. Remove the PSU slot cover from the S5048F-ON switch using a small #1 Phillips screwdriver.
  2. Remove the PSU from the electro-static bag.
  3. Insert the PSU into the switch PSU slot—insert the exposed PSU connector first).
    The PSU slot is keyed so that you can only fully insert the PSU in one orientation. When you install the PSU correctly, it snaps into place and is flushed with the back of the switch.

  4. Plug in the appropriate AC 3-prongs cord from the switch PSU to the external power source.
  5. Repeat steps 1 through 4 if you have a redundant PSU using the second PSU slot on the S5048F-ON switch.

    NOTE: : The S5048F-ON switch powers up when you connect the cables between the power supply and the power source.
