Remove the top cover

Procedure

1. Make preparations for this task.
   1. Power off the node (see Power off the node); then, disconnect all external cables from the node.
      Note

      If necessary, press the release clip with a flat-head screwdriver to remove an external network cable from the rear of a 2U node.
      
      
   2. Remove the node from the chassis (see Remove a node from the chassis); then, carefully lay the node on a flat, static-protective surface, orienting the node with the front toward you.
      Note

      • When removing the node, note the node tray number and make sure to install the node in the same tray from which it was removed. Reinstalling the node into a different tray requires the node to be reconfigured.
      • For safety, make sure to hold the node with both hands when lifting the node.
2. Remove the top cover from the node.
   1. Press the release button on the side of the top cover.
   2. Slide the top cover toward the rear of the node; then, lift it up from the node and place it on a flat and clean surface.
      Important

      • Service label is located on the inside of the top cover (see Identify the system and access the Lenovo XClarity Controller).
      • For proper cooling and air flow, install the top cover before powering on the node. Operating the node with the top cover removed might damage the components.
