Removing and replacing a fan module

Use this procedure to replace a faulty fan module in an FlashSystem 9500 node canister with a new one received from stock.

About this task

Each node canister contains five fan modules, which are accessible when the node canister is removed from the control enclosure.

Attention:
  • Do not remove the node canister and faulty fan module before the replacement fan is available. After a fan module is removed, this replacement procedure must be completed within 16 minutes to ensure that the components do not shut down due to excessive temperatures.
  • Electrostatic discharge precaution symbol When you replace this part, you must follow recommended procedures for handling electrostatic discharge (ESD)-sensitive devices.
  • A Phillips screw driver is required to remove the canister cover.

Procedure

  1. Follow Procedure: Powering off a node canister to verify that the hosts will not lose access to data in volumes.
  2. Remove the node canister, as described in Removing and reseating a node canister.
  3. Remove the cover, as described in Removing and replacing the cover of a node canister.

Removing the fan module

  1. Remove the replacement fan module from its packaging.
  2. Identify the faulty fan module.

    The Event Log indicates the fan and node that are causing the error. The fix procedure in the management GUI provides the location of the node canister. As Figure 1 shows, the fan modules are numbered 1 to 5 within the node canister. Note that Figure 1 shows the fans with the air baffle removed. The air baffle does not need to be removed to remove or replace a fan

  3. Hold the fan module between your finger and thumb at the blue touch points. Squeeze gently and lift the fan module out of the node canister, as Figure 2 shows.

Replacing the fan module

  1. Install the replacement fan module into the vacant fan slot. Ensure that the cable is not caught under the fan module.
  2. Install the canister cover, as described in Removing and replacing the cover of a node canister.
  3. Reinsert the node canister, as described in Removing and reseating a node canister.
  4. Reconnect the power and data cables into the ports from which they were removed.
  5. If the control enclosure is powered and the node canister is correctly installed, the node canister starts automatically.
    1. If the node canister is not correctly installed, remove it and repeat the installation procedure.
  6. When the node canister is back online, check the Event Log for any new events that might indicate a problem with the reassembly.
