Remove the front OCP 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. Remove the front OCP module (see Remove the OCP module).
2. Loosen the screw that secures the grounding cable; then, remove the grounding cable from the front OCP cage.

3. Remove the front OCP cage from the node.
   1. Remove all the screws that secure the cage to the node on the left and right sides of the node.
   2. Disconnect the XCC management module cable from the OCP cage.
   3. Remove the two screws that secure the front OCP cable to the OCP cage (1 in the illustration). Then, disconnect the shorter OCP cable (1a in the illustration) from the system board and lift this cable away from the front air baffle.
      Note

      To prevent damage on the OCP cable, avoid using excessive force on the OCP cable screws.
