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
®
to
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.

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.)

and SES error messages, see the DS4243, DS2246, DS4486, and

Set disk shelf IDs
1. Connect power cords to the disk shelf, and then turn on the power to the disk shelf.
2. Visually verify that the ID for each disk shelf is unique, and if not, set the
disk shelf ID:
a. Remove the left ear cover.
b. Press and hold the shelf ID button until the first digit blinks.
c. Press the button until the correct number is displayed.
d. Repeat steps band cfor the second digit.
e. Press and hold the button until the second number stops blinking.
Result: Both numbers blink and the operator display panel fault LED illuminates
in about five seconds.
f. Power-cycle the disk shelf to make the new disk shelf ID take effect.
For the detailed procedure, see the DS4243, DS2246, DS4486, and DS4246 Disk
Shelf Installation and Service Guide.

ID

Note: A valid shelf ID is 0-98. FAS20xx and FAS22xx systems have the
internal shelf ID preset to 00.
Note: A unique shelf ID is required for each SAS shelf within the entire
storage system. If your storage system has SAS and FC shelves, shelf IDs do
not need to be unique between the SAS and FC shelves. (FC shelf IDs
continue to be unique within each FC loop. SAS shelf IDs continue to be
unique to all other SAS shelves in the storage system, including internal shelf
IDs for FAS20xx and FAS22xx systems.)
Note: Connect power supplies to different power sources for resiliency.
Cable the system
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 examples, see the Universal SAS and ACP Cabling Guide.

Install the disk shelf in a rack
If the DS2246 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
To reduce the weight of the disk
shelf, remove the power supplies
and IOMs before lifting.
49 lbs (22 kg)
Note: If you are installing the DS2246
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.

Ground yourself
Ground yourself to the storage system chassis using the grounding leash that came with your storage system.
Note: You do not need to ground DS2246 disk shelves; grounding is done through the power cords.
