Before You Start

Before you install host boards, make sure that the following steps have been completed.

• Refer to the Host Board and Memory Guide for more information, including supported host board types, supported combinations, and important notes. You can find it at Support > Technical Support > Scale-out NAS > Downloads.

To install host boards on a storage system that is already in operation:

• Shut down the applications and the system first before installing a host board.
• Export the NVRAM first before making any host board changes. When you remove, insert, or change a host board, the system will reset to the default system and NAS settings to prevent the previous settings from creating unexpected behaviors with the new hardware change.

Install a Host Board

1. Unfasten the retention screw from the controller that you want to install the host board (A), and hold the rim then remove the controller from the system (B).

   

2. Remove the screw that secures the dummy cover to the enclosure.

   

3. Orient the new host board to the controller’s guide pin, place it carefully, then tighten the thumbscrew to secure it in place.

   

4. Insert the controller carefully into the module slot. When you feel a contact resistance, push the controller with a small but careful force, then secure the controller to the enclosure with the retention screw.
