Replace a fan — FAS500f
You replace a fan with a new fan module when it fails.
Step 1: Shut down the impaired controller
To shut down the impaired controller, you must determine the status of the controller and, if necessary, take over the controller so that the healthy controller continues to serve data from the impaired controller storage.
If you are using NetApp Storage Encryption, you must have reset the MSID using the instructions in the “Returning SEDs to unprotected mode” section of the ONTAP 9 NetApp Encryption Power Guide.
If you have a SAN system, you must have checked event messages (
event log show) for impaired controller SCSI blade.
Each SCSI-blade process should be in quorum with the other nodes in the cluster. Any issues must be resolved before you proceed with the replacement.
If you have a cluster with more than two nodes, it must be in quorum. If the cluster is not in quorum or a healthy controller shows false for eligibility and health, you must correct the issue before shutting down the impaired controller; see the Administration overview with the CLI.
If you have a MetroCluster configuration, you must have confirmed that the MetroCluster Configuration State is configured and that the nodes are in an enabled and normal state (
metrocluster node show).
If AutoSupport is enabled, suppress automatic case creation by invoking an AutoSupport message:
system node autosupport invoke -node * -type all -message MAINT=number_of_hours_downh
The following AutoSupport message suppresses automatic case creation for two hours:
cluster1:*> system node autosupport invoke -node * -type all -message MAINT=2h
Disable automatic giveback from the console of the healthy controller:
storage failover modify –node local -auto-giveback false
When you see Do you want to disable auto-giveback?, enter
Take the impaired controller to the LOADER prompt:
If the impaired controller is displaying… Then…
The LOADER prompt
Go to Remove controller module.
Waiting for giveback…
Press Ctrl-C, and then respond
System prompt or password prompt (enter system password)
Take over or halt the impaired controller from the healthy controller:
storage failover takeover -ofnode impaired_node_name
When the impaired controller shows Waiting for giveback…, press Ctrl-C, and then respond
Step 2: Remove the controller module
You must remove the controller module from the chassis when you replace a fan module.
Make sure that you label the cables so that you know where they came from.
If you are not already grounded, properly ground yourself.
Unplug the controller module power supplies from the source.
Release the power cable retainers, and then unplug the cables from the power supplies.
Insert your forefinger into the latching mechanism on either side of the controller module, press the lever with your thumb, and gently pull the controller a few inches out of the chassis.
If you have difficulty removing the controller module, place your index fingers through the finger holes from the inside (by crossing your arms).
Using both hands, grasp the controller module sides and gently pull it out of the chassis and set it on a flat, stable surface.
Turn the thumbscrew on the front of the controller module anti-clockwise and open the controller module cover.

Step 3: Replace a fan
To replace a fan, remove the failed fan module and replace it with a new fan module.
You can use the following video or the tabulated steps to replace a fan:
Identify the fan module that you must replace by checking the console error messages or by locating the lit LED for the fan module on the motherboard.
Remove the fan module by pinching the side of the fan module, and then lifting the fan module straight out of the controller module.
Align the edges of the replacement fan module with the opening in the controller module, and then slide the replacement fan module into the controller module.
Step 4: Reinstall the controller module
After you replace a component within the controller module, you must reinstall the controller module in the system chassis and boot it.
Close the controller module cover and tighten the thumbscrew.

Insert the controller module into the chassis:
Ensure the latching mechanism arms are locked in the fully extended position.
Using both hands, align and gently slide the controller module into the latching mechanism arms until it stops.
Place your index fingers through the finger holes from the inside of the latching mechanism.
Press your thumbs down on the orange tabs on top of the latching mechanism and gently push the controller module over the stop.
Release your thumbs from the top of the latching mechanisms and continue pushing until the latching mechanisms snap into place.
The controller module begins to boot as soon as it is fully seated in the chassis. Be prepared to interrupt the boot process.
The controller module should be fully inserted and flush with the edges of the chassis.
Recable the system, as needed.
Return the controller to normal operation by giving back its storage:
storage failover giveback -ofnode impaired_node_name
If automatic giveback was disabled, reenable it:
storage failover modify -node local -auto-giveback true
Step 5: Return the failed part to NetApp
Return the failed part to NetApp, as described in the RMA instructions shipped with the kit. See the Part Return & Replacements page for further information.
