Replacing the operator display panel requires you to halt your
system.
IOMs are hot-swappable in HA pair configurations (not single-
controller single-path configurations).
Power supplies and disk drives are hot-swappable. (Replace the
power supply within two minutes of removal to minimize disruption
to the disk shelf's airflow.)
For component and shelf replacement instructions, LED behavior,
and SES error messages, see the DS4243, DS2246, DS4486, and
DS4246 Disk Shelf Installation and Service Guide.

Hot-adding disk shelves
If you are hot-adding disk shelves to an existing storage system, see the applicable document
for the system requirements and procedure:
For storage systems, see the DS4243, DS2246, DS4486, and DS4246 Disk Shelf Installa-
tion and Service Guide.
For MetroCluster systems using SAS optical cables, see Configuring a stretch MetroCluster
system with SAS disk shelves and SAS optical cables.
For MetroCluster systems using FibreBridge 6500N bridges, see Configuring a MetroCluster
system with SAS disk shelves and FibreBridge 6500N bridges.
These documents can be found on the NetApp Support Site at support.netapp.com.
Alternate Control Path (ACP) capability
For maximum storage availability and stability, storage systems with DS2246 disk shelves
have the option to use the ACP capability. ACP is a protocol that enables Data ONTAP
manage and control the DS2246 disk shelf storage subsystem. It uses a separate network
from the data path so that it can independently perform recovery whenever certain
interruptions are detected in the data path.
To use the ACP capability, you must cable the ACP ports on the disk shelves and connect
the disk shelves to the dedicated network interface on each storage system controller. At
system setup, you enable ACP functionality by configuring ACP parameters. If your storage
system does not have a dedicated onboard network interface for ACP, you assign one at
system setup.
Standard ACP cabling rules apply to all storage systems and can be found in the DS2246
Installation and Service Guide. ACP functionality, configuration, and enabling information
can be found in the Data ONTAP Storage Management Guide.
Note: If at initial storage system setup you choose not to use the ACP capability, you can
use it later by cabling the ACP connections and enabling ACP by running setup again.
