Removing the fans: 2145-SV1

You can remove any of the six fans in a SAN Volume Controller 2145-SV1 node.

Before you begin

DANGER

Multiple power cords. The product might be equipped with multiple power cords. To remove all hazardous voltages, disconnect all power cords. (L003)

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. 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.
   Note: 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 when power is turned off.
3. Disconnect both power cords.
4. Pull the node out of the rack on the slide rails, if needed, to reveal the top covers.
5. Remove the top back cover, as described in Removing the top covers: 2145-SV1.
6. Locate the appropriate fan. The node has six fan positions that are numbered from left to right, as shown in Figure 1.
