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 Installation 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
Two IOMs
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.)
Shelf IOMs are not hot-swappable in storage systems that
are single-controller single-path configurations.
Mixing IOM3 and IOM6 in the same disk shelf is not supported.
For component replacement instructions, LED behavior, and SES
error messages, see the DS4243, DS2246, DS4486, and
DS4246 Installation and Service Guide.

For maximum storage availability and stability, storage systems with disk shelves have
the option to use the ACP capability. ACP is a protocol that enables Data ONTAP® to
manage and control the 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 Universal SAS and ACP Cabling 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.

Documentation
For the most current information about supported Data ONTAP releases, platforms, SAS disk shelves, disk drives,
and SAS cables, see the Hardware Universe on the NetApp Support Site at support.netapp.com.

For more disk shelf and safety information, see the
DS4243, DS2246, DS4486, and DS4246 Disk Shelf
Installation and Service Guide.
Ground yourself
All documentation can be found on the NetApp
Support Site at support.netapp.com.
Ground yourself to the storage system chassis using the grounding leash that came with your storage system.
Note: You do not need to ground disk shelves; grounding is done through the power cords.
2
Installing the disk shelf in a rack
If the disk shelf did not come in a system cabinet, you must install it in an equipment rack using the four-post rail kit or the two-post telco tray kit that came with
your disk shelf. See the rack installation flyer that came with the rack kit for detailed instructions.
LIFTING HAZARD
CAUTION
Note: If you are installing the disk shelf in a
two-post mid-mount installation, you must use
the mid-mount telco kit, which includes brackets,
in addition to the two-post telco tray kit.

To reduce the weight of the
disk shelf, remove the
power supplies and IOMs
before lifting.
Set disk shelf IDs
1. Connect power cords to the disk shelf and turn on the power to the disk shelf.
Note: A valid shelf ID is 0-98.
Note: Depending on the disk drive type, your disk shelf might have two or four

Cable the system
Note: To cable MetroCluster systems with SAS optical cables or
FibreBridge 6500N bridges, see the applicable guide: Configuring a
stretch MetroCluster system with SAS disk shelves and SAS optical
cables or Configuring a MetroCluster system with SAS disk shelves
and FibreBridge 6500N bridges.
If you are using HBAs, they must already be installed in the storage system.
1. Cable controllers.
See the documentation that came with your storage system for how to cable the controllers.
2. Cable disk shelves.
Following are steps to cable two common configurations. For SAS and ACP rules, and more cabling configurations, see the Universal SAS and ACP Cabling Guide.
