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.
2
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.

Set disk shelf IDs
1. Connect power cords to the disk shelf, and then turn on the power to the disk shelf.
Note: Connect power supplies to different power sources for resiliency.
2. Visually verify that the ID for each disk shelf is unique, and if not, set the
disk shelf ID:
3
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 b and c for 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.

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.

Boot the system and proceed with setup
- See the Installation and Setup Instructions that came with your storage system for booting your storage system and for system setup.
- To take advantage of the ACP capability, you can enable it at setup or later. See the Data ONTAP Software Setup Guide for the setup worksheet and other setup information.

addition to the two-post telco tray kit.

ID
button
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: 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 .
