Removing the SAN Volume Controller 2145-8A4 fans

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.
Perform the following steps to remove a failed fan:
  1. Turn off the node while ensuring that its data is mirrored and synchronized. See MAP 5350: Powering off a SAN Volume Controller node for more information.
  2. Remove the cable-retention bracket and disconnect the power cable from the node. See Removing the cable-retention bracket.
  3. Remove the node from the rack and place it on a flat, static-protective surface. See Removing the SAN Volume Controller from a rack.
  4. Remove the top cover. See Removing the top cover.
  5. Reconnect the power cord and then turn on the node.
    Attention: Operating the node for extended periods of time (more than 30 minutes) with the cover removed might damage server components.
  6. Determine which fan to replace by checking the LEDs on the system board. Each fan has an LED next to it. A lit LED indicates the fan to replace.
  7. Turn off the node and then disconnect the power cord again.
  8. Remove the failed fan.
    1. Disconnect the fan cable from the system board.
      Note: Make a note of the routing of the fan cable to the connector. You will have to route the fan cable the same way when you install the fan.
    2. Grasp the top of the fan with your index finger and thumb and lift the fan out of the server.
