Replacing a 7x20 Fan Module

Language:

Caution - Operating a controller for over 60 seconds with fans removed reduces the effectiveness of the cooling system. For this reason, the replacement fan should be unpacked in advance and ready to insert into the controller chassis as soon as the faulted fan is removed.

Fan modules are hot-swappable and can be removed and installed while the storage controller is running without affecting other hardware capabilities.

7120 or 7320: The fan modules and status indicators are hidden under a fan door in the 7120 and 7320 storage controllers. Components may differ slightly between the 7120 and 7320, however service procedures for each are identical. The illustration shows the 7320 controller.

Caution - The storage controller might overheat and shut down if the door is left open for more than 60 seconds.

7420: The following illustration shows the fan modules in the 7420 storage controller.

To locate the faulted component, go to Maintenance > Hardware > Fan and click the row with an amber indicator.
The component is highlighted in the diagram.
Extend the controller from the rack as described in Extending the Storage Controller from the Rack.

7120 or 7320: To replace the fan module:

Open the fan module door by unlatching its release tabs.

Caution - The storage controller might overheat and shut down if the door is left open for more than 60 seconds.

If the system is still powered on, identify the fan module with the lit fault indicator.
Using thumb and forefinger, squeeze the tabs together to pull the fan module up and out.
Insert the replacement fan module into the slot and apply firm pressure to fully seat it.
On the replaced fan module, verify that the Fan OK indicator is lit, and that the fault indicator is not lit.
Close the door immediately to maintain airflow in the storage controller.

7420: To replace the fan module:

Lift the latch at the top of the fan module to unlock the fan module, and pull the fan module out.

Caution - The fan module must be replaced within 60 seconds because the storage controller might overheat and shut down.

Verify that the controller's Top Fan status indicator, Service Required status indicators, and the Locator status indicator/Locator button are not lit.
Push the release tabs on the side of each rail and slowly slide the storage controller into the rack.
Go to the Maintenance > Hardware screen of the BUI. Click the right-arrow icon for the controller and then click Fan to verify that the online icon is green for the newly installed fan module.
