  • Touch the static-protective package that contains the component to any unpainted metal surface on the server; then, remove it from the package and place it on a static-protective surface.

CAUTION

Power adapters to the node must be of the same brand, power rating, wattage or efficiency level.

Note
  • Depending on the model, the enclosure might look slightly different from the illustrations in this section.
  • ThinkEdge SE100 1U2N and 1U3N Enclosure only support 300W power adapters. For supported power adapters, see Lenovo ServerProven website.

Procedure

  1. Make preparation for this task.
    1. Remove the middle cover.

      Remove the middle top cover of 1U2N enclosure

      • Loosen the six captive screws on the middle top cover.
      • Lift up the middle top cover from the enclosure, and place it on a flat clean surface.
      Figure 1. Removing the middle top cover of 1U2N enclosure

      Remove the middle top cover of 1U3N enclosure

      • Loosen the eight captive screws on the middle top cover.
      • Lift up the middle top cover from the enclosure, and place it on a flat clean surface.

    2. Remove the rear cover.
      1. Loosen the six captive screws on the rear top cover.
      2. Lift up the rear top cover from the enclosure, and place it on a flat clean surface.


    3. Remove the air baffle. Pinch the air baffle by the blue touch points, and carefully lift the air baffle out of the enclosure.
