Remove the enclosure air baffles

Use this information to remove the enclosure air baffles.

Procedure

Figure 1. Enclosure air baffles removal

1. Make preparations for this task.
   1. Turn off the solution and peripheral devices and disconnect the power cords and all external cables (see Power off the compute node).
   2. If the solution is installed in a rack, remove the solution from the rack (see Remove the server/solution from the rails).
      CAUTION

      To avoid a drop hazard, slide the enclosure out of the rack slowly and steadily. Make sure to grip the enclosure with both hands when pulling it forward on the slide rails and lifting it out of the rack. Use safe practices when lifting.
   3. Remove the components listed below from the enclosure in the following order:

      • Compute node(s) (see Remove a compute node from the enclosure).

      • System Management Module 2 (see Remove the hot-swap SMM2).

      • Power supplies (see Remove a hot-swap power supply).

      • Enclosure cover (see Remove the enclosure cover).

      • Upper power distribution board (see Remove the upper power distribution board).

2. Remove the enclosure air baffles from the enclosure.
   1. Disengage the air baffle marked with from the hook on the side of the power supply bay 1 and lift it out of the enclosure.
   2. Disengage the air baffle marked with from the hook on the side of the power supply bay 2 and lift it out of the enclosure.
   Attention

   For proper cooling and airflow, replace the enclosure air baffles before you turn on the compute node. Operating the node without the enclosure air baffles might damage node components.
