Removing the fans: 2145-CG8 or 2145-CF8

You can remove a fan on a SAN Volume Controller 2145-CG8 or 2145-CF8 node.

Before you begin

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.

About this task

Important: You can hot swap a fan. However, using MAP 5350: Powering off a node 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:

Procedure

  1. Read the safety information to which Preparing to remove and replace parts refers.
  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 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 volumes (VDisks) 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. Slide the node forward to remove the cover and expose the fans, as described in Removing the top cover: 2145-CG8 or 2145-CF8.

    Figure 1 shows fan locations within the SAN Volume Controller 2145-CG8 or 2145-CF8 node.

    •  1  Fan 1
    •  2  Fan 2
    •  3  Fan 3
    •  4  Fan 4
    •  5  Fan 5
    •  6  Fan 6
    •  7  Fan tabs
    •  8  Fan connector on the system board
    •  9  Fan connector
    •  10  Side view of fan showing air-flow indicator

    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.

  4. Grasp the orange fan tabs on both ends of the existing fan and pull it up out of the node. If you are removing fans 3 or 4, lift up the clear tab on the DIMM air baffle first.

    Figure 2 shows a fan being removed from the node.

    Attention: To ensure proper operation, replace a failed fan within 30 seconds.
  5. If you are instructed to return the fan, follow all of the packaging instructions, and use any packaging materials for shipping that are supplied to you.
