Hot-Swapping the AT-FCX module

About the AT-FCX module

The AT-FCX module controls the external disk shelf LEDs. The module communicates with your storage appliance through the Fibre Channel port that is connected to the backplane of the disk shelf.

Location of the AT-FCX module

The module is plugged into the backplane at the back of the disk shelf enclosure.

Assumptions about this procedure

The assumptions about this procedure are that the AT-FCX modules on the disk shelf use multipath connections to your storage appliance and that you are hot-swapping an AT-FCX with another AT-FCX.

Caution
If you attempt to hot-swap the AT-FCX on a disk shelf that does not have multipath connections, you will lose all access to the drives on this disk shelf as well as those below it.

Hot-swapping a module

To hot-swap a module, complete the following steps.

Note
To hot-swap a module on a disk shelf in a cluster, see the cluster guide for your filer.

Step	Action
1	Verify that your storage appliance meets the minimum software requirements to support the disk shelf and module combination. See the System Configuration Guide at http://now.netapp.com for more information.
2	Ground yourself to the system chassis using the grounding leash.
3	From the storage appliance console, enter the following command to disable the loop in which the failed module is a connection: storage disable adapter adaptername The Data ONTAP System Administrator's Guide (7.0.1 or later) provides more information about these commands.
4	Disconnect the module that you are removing from the loop cabling.
5	Using the thumb and index finger of both hands, press the levers on the CAM mechanism on the module to release it and pull it out of the disk shelf.
6	Slide the replacement module into the slot at the rear of the disk shelf and push the levers of the CAM mechanism into place. Caution Do not use excessive force when sliding the AT-FCX into the disk shelf; you might damage the connector.
7	Reconnect the loop cabling.
8	From the storage appliance console, enter the following command to enable the loop in which the replacement AT-FCX is a connection: storage enable adapter adaptername
