Replacing a ZS5-4 Fan Module

Fan modules are hot-swappable and can be removed and installed while the storage controller is running without affecting other hardware capabilities. Use the following procedure to replace a ZS5-4 fan module.

Before You Begin

Unpack the replacement fan module and get it ready to insert into the controller chassis as soon as the faulted fan is removed.

1. Identify the faulted fan module.

   • If you are not physically at the system, go to the Maintenance > Hardware section of the BUI, click the right-arrow icon for the controller, click Fan, and note the ID of the faulted fan module, which has an amber icon. To highlight the location of the fan module in the controller picture, click on the fan module ID. To view details about the faulted fan module, click its information icon and then click Active Problems.

   • If you are physically at the system, the amber Service Action Required indicator on the fan module should be lit.

2. Extend the controller from the rack as described in Extending the Storage Controller from the Rack.
3. Lift the green handle at the top of the fan module to unlock the module, and pull the module straight up and out.

   Caution  -  Excessive movement or rocking of the fan module during removal can cause damage to the internal connector on the fan module board. When removing a fan module, do not rock it back and forth.

4. Position the replacement fan module so the connector on the bottom of the module is aligned with the connector on the inside of the slot and all keying and labeling are correctly positioned.

   The fan modules are keyed to ensure that they are installed in the correct orientation.

   
   
5. Slide the fan module into the slot until it stops.
6. Press downward on the top of the fan module, on the Press Here to Latch label, until the fan module is fully seated.
7. Replace the top cover on the chassis.
8. Return the controller to the normal rack position by pushing the release tabs on the side of each rail while slowly pushing the storage controller into the rack.
9. Verify that the green OK indicator is lit.
10. Verify that the Top Fan indicator and the Service Action Required indicator on the server front panel are not lit.
11. Go to the Maintenance > Hardware screen of the BUI. Click the right-arrow icon for the controller, click Fan, and verify that the status icon is green for the newly installed fan module. To view details about the new fan module, click its information icon.
