Replacing the fans: 2145-DH8

You can replace any of the four fans on a SAN Volume Controller 2145-DH8 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)
Multiple plugs: first set
or
Multiple plugs: second set
or
Multiple plugs: third set

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

About this task

Important: You can hot swap a fan. However, using MAP 5350: Powering off a node to power off the node avoids risking an abrupt power failure on the node, which avoids the possibility of corrupting data.

To replace the fans, complete the following steps.

Procedure

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

    •  3  Fan 3
    •  4  Fan 4
  4. Orient the new fan over the appropriate fan slot in the fan-assembly bracket so that the fan connector aligns with the connector on the system board. This alignment assures that the air-flow indicator arrow on the side of the fan is pointing to the rear of the node.
  5. Insert the fan into the fan slot in the fan-assembly bracket, and press it down until it is seated.
  6. Make sure that all cables, adapters, and other components are installed and seated correctly, and that all internal cables are correctly routed.
  7. Replace the top cover.
  8. If you removed the node from the rack, replace the node in the rack.
  9. If you removed any Fibre Channel or Ethernet cables, replace them in the same ports from which they were removed.
  10. If you removed the power cords, replace the power cords and the cable-retention brackets.
  11. Lift the locking levers ( 1  in Figure 2) on the slide rails and push the server  2  all the way into the rack until it clicks into place.
