Remove the fan cage

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.
   3. Remove the top cover (see Remove the top cover).
   4. If the GPU air duct is installed in the node, remove it (see Remove the GPU air duct).
   5. If the internal adapter bracket is installed and blocks the way of removing the fan cage, disconnect all the cables from the internal adapter; then, remove the internal adapter bracket from the node (see Remove the internal adapter bracket).
2. Disconnect all the fan cables from the system board.
3. Remove the fan cage from the node.
   1. Pivot the release plunger to the unlocked position.
   2. Carefully push the fan cage assembly toward the rear of the node; then, lift the fan cage out of the node.
