Removing the SAN Volume Controller 2145-CF8 fans

You can remove a SAN Volume Controller 2145-CF8 fan.

Take precautions to avoid damage from static electricity. Wear an anti-static wrist strap and use a static-protected mat or surface. For more information, see Handling static-sensitive devices.

Important: You can hot swap a fan. However, using MAP 5350 to power off the node through proven methods avoids risking an abrupt power failure on the node, which avoids the possible corruption of data.

Perform the following steps to remove a failed fan:

Read the safety information to which Preparing to remove and replace parts refers.
Optional: Follow the procedure in MAP 5350: Powering off a SAN Volume Controller node to verify that the node data is mirrored and synchronized, and that there are no dependent virtual disks (VDisks) before turning off the node.

Important: If you decide to hot swap the fan, use MAP 5350 to make all of the necessary checks that ensure 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 VDisks on the node. With the partner node available and no dependent VDisks on the node, you do not lose access to data if this node accidentally powers off.
Slide the node forward to remove the cover and expose the fans, as described in Removing the SAN Volume Controller 2145-CF8 top cover.

The node has six fan positions that are numbered right to left. The LED near the connector of the failing fan assembly is lit, unless you remove the power cable.
Grasp the orange fan tabs on both ends of the existing fan and pull it up out of the server. If you are removing fans 3 or 4, lift up the clear tab on the DIMM air baffle first.
