Take precautions to avoid damage from static electricity. Wear an anti-static wrist strap and use a static-protected mat or surface.

To remove the fans, complete the following steps:

1. Read the safety information.
2. Optional: Follow the procedure in MAP 5350: Powering off a node to verify that hosts will not lose access to data in volumes before you power off the node.
   Important: If you decide to hot swap the fan, use MAP 5350 to make all of the necessary checks. MAP 5350 ensures that the partner node in the I/O group can take over all I/O group operations, if necessary, and that there are no dependent volumes on the node. With the partner node available and no dependent volumes on the node, you do not lose access to data if this node accidentally powers off.
3. Remove the top cover.

   To ensure proper system cooling, do not remove the top cover for more than 30 minutes during this procedure.

   The node has four fan positions that are numbered from right to left, as shown in Figure 1.
